Yes, NVDA does work with 64-bit vista, I've tried it out on a friend's machine. As for orca, linux, and windows, I don't know how that would work, but I would imagine that it would work.

I know there is a 64 bit version of Python, but are you sure that NVDA fully runs on 64 bits. Aren't any of the APIs it uses dependent on 32 bits? How about the software synthesizers? I am not saying that it does not work as well on 64 bits, but am seeking further clarification. Similarly, I'm curious how well Orca and VoiceOver work on 64 bits if anyone knows. Would it be possible, for example, to make the machine dual boot with 64 bit Linux and Orca on another partition from the 32 bit Vista?

I haven't installed JAWS 10.xx on anything yet so cannot comment on it. My Vista box and JAWS get along relatively well and I find that, excepting many applications which JAWS 9 does not support adequately, the system works acceptably. I also find that having System Access around (I guess everyone has the "to go" version at their fingertips) is helpful as Monster Matt has made some very useful Vista things work really well with SA that are highly problematic with JAWS. On some specifics: JAWS 9 does great with IE, VisualStudio (using the scripts developed on this list) and a reasonably adequate job with Office 2007 and other programs I find useful. It is useless in the Vista voice recognition system (SA kicks ass) and most of the multi-media stuff that you might enjoy using to turn your new PC into a DVR or for downloading and playing movies from bit torrent and other sites. Office 2007 works reasonably well with both JAWS and SA on Vista and is not a 64 bit program but, like all Intel processors from 386 on forward, it can "step down" and run programs designed for earlier generation chips. I doubt Vista supports any 16 bit Windows programs but most Win32 applications should still work. The 32 bit Vista builds can only address 3.5 gb of memory with SP1, previously, it could only address 2 gb so this is an improvement. Of course, the four gb in my HP has been partially unused since I got the thing. I haven't done much more than fiddle around with Window-Eyes 6.xx on Vista and it worked pretty good. I wrote a bunch of blog entries last summer comparing and contrasting JAWS, WE and SA as they were then with Vista which might be of some value to you if you go to BC and search the blog on related terms. If SA and WE are at all like JAWS internally, it will probably be quite some time until any of them start supporting the 64 bit architecture. There are likely assumptions all over the place about the size of different elements being 32 bits and not 64. Porting from one to another, in a modern, clean code base will be less hard than an older one that has been hacked and repaired many times over the years as is the case with JAWS and, I'll assume parts of WE as well. SA has a very new code base and a whole lot less code to port so Monster Matt may be able to do it in relatively short order. I'd also guess that the NVDA guys (I haven't looked at their source with this problem in mind), because they are based almost entirely on documented API and not too much if at all on hooking hacks, may be able to take the jump more easily than the others. I find it discouraging in general that no current Windows screen reader supports the off-the-shelf PCs available at the consumer electronics stores anymore. When I worked at FS, we would often talk about trying to make sure JAWS would "work with the PC that will show up under the Christmas tree..." in any given year. More often than not, we made it (we were late with a default copy protection scheme that didn't require a floppy drive) but this year, it appears as if the only 64 bit screen readers will be Orca and VoiceOver and nothing (as far as I can tell) for Windows. Regarding price and performance for a standard use PC with screen reader, I think we're starting to hit a wall of diminishing returns. Lots of the extra horsepower and memory is great for multi-media stuff and really serious number and database crunching. Frankly, I don't do any of that kind of thing and the most compute intensive things I use (probably the HRTF functions in Direct X) do not, at least in my applications, bog down a relatively old 32 bit single core XP laptop and don't even come close to a bottleneck on my year and a half old Vista machine. I must say that the 64 bit OSX Leopard edition on Macintosh is really peppy but comparing that to Windows is not a fair way to judge as the software running is also vastly different. I find that for price/performance for a solid PC that will do everything I want it to the best prices are available at www.dell.com/outlet where you can get a lease return with full guarantee that will contain a really kicking processor, decent sized hd, as much memory as you will need or want for about $350 and a very adequate PC for around $150. If you want to take the plunge into Macintosh, for a little over $1000 you can get a kick ass laptop and run XP under VMWare with the screen reader of your choice in a separate Window. Other than web browsing related tasks where JAWS, WE, SA, etc. are all better) , I find that I can get almost everything I need to do done well on a Macintosh with VoiceOver quickly and with a level of stability I couldn't dream of on a PC with a screen reader (at one point, I kept my Macintosh running non-stop for four weeks without a single need to reboot until I installed some new software). Ok, you asked for perspectives and I'm in a NyQuil haze after walking some distance through Cambridge in a downpour yesterday so this is what you get...

My hope was to get good value on the computer and from the store's "Geek Squad" service that delivers and installs it, including a wireless network. I had not bought a new computer in several years and was not familiar with hardware differences in current offerings. I knew I wanted the home version of Windows Vista, and asked the senior technical representative on duty for a recommendation on a computer that used "industry-standard" components as much as possible, thereby maximizing compatibility with the screen reader technology that I used. I emphasized memory and hard disk space over a graphics card and monitor intended for games. The representative indicated that he understood my needs and recommended a Del computer with relatively large memory and hard disk specifications. Last Saturday, a Geek Squad technician delivered the computer to my home, installed it and the wireless network. At the end of the process, he mentioned that it was a 64-bit computer. I was shocked and dismayed as I knew that no screen reader worked with 64-bits yet. As evidence, I had him run a copy of JAWS, which immediately said it would not work on a 64-bit computer. The technician acknowledged that it had been a mistake to recommend such a computer, particularly in the context of my request for industry-standard components, and without even asking me if 64-bits was an acceptable specification. He said he would return on Wednesday with a replacement, 32-bit computer. It had not occured to me to specify 32-bits because I had perceived it, although changing over time, as still being a feature of high-end computers intended for a circumscribed set of resource-intensive applications, rather than for customers at a Best Buy store with a typical consumer interest in running a range of applications, including ones found on the Internet. The technician was scheduled to arrive between noon and 4 PM on Wednesday, yesterday. I took a vacation day from work to be there, though I had not wanted to lose vacation time for this originally. Despite repeated calls I made during the day to confirm the appointment, the technician did not call me until about 4:30 from the Best Buy store, where he said he discovered no 32-bit computers available. He discussed the problem with others there and said their recommendation was to load a 32-bit version of Vista on the 64-bit computer I purchased. Although they had little actual experience with this, and were unable to contact a Del representative to confirm the approach, they were confident it would work except that only 3.5 out of the 6 gigabytes of memory would be addressable because that was an upper limit for 32-bit Windows. I asked but they were not willing to call other Best Buy stores in the greater DC area to check if they had a 32-bit Del computer in stock. I said I would go along with this plan, now scheduled for a Sunday installation at my home, but that I would have to do immediate testing of various programs to assure myself that there were no compatibility problems. Since it is a few days away, I thought it best to schedule the re-install and do some additional research in the meantime. With that background, I am seeking information and advice from list members on a few questions. Will there be no compatibility problems from loading 32-bit Vista and drivers on a 32-bit computer. Specifically, it is a Del Inspiron Model I530-110B. Is 3.5 gigabytes the maximum addressable memory in this case? Would the same limit be true on a 32-bit computer? I had also purchased Microsoft Office Professional 2007. They said that the same version runs on either 32-bit or 64-bit computers. Is that the case? Does anyone have more experience to share about Best Buy and Geek Squad? The representatives involved say that they usually sell 64-bit computers now. I find this surprising since I thought a majority of software still requires 32-bits today. Is their statement credible? Is this the default retail practice now?
