So by this I take it you are saying that you can see cursor problems
with the Mini? I will get my first look Thursday night.
Also, the problems with full video refresh at 1920 x 1080 were
alluded to during the MacWorld keynote. The Mini can drive the 23"
Apple Cinema display (1920 x 1200), but it may struggle to refresh
this display via the DVI port. Apple announced at the keynote the
H.264 implementation in QuickTime 7 will be optimized for 720P (on
the source side of the equation).
You mentioned that you were using the VGA port, presumably in 1920 x
1080 mode. Have you been able to determine whether this output is
1080@30i our 1080@ 60P? This could make a huge difference in video
refresh, if the graphics chip needs only push ~63 Msamples versus
~126 Msamples to the display.
As you noted, this is just the first box in what is likely to be a
new series of products. By the time Apple actually admits that the
Mini is going to target the media center market, I suspect it will
have evolved a bit.
As for the 256MB of RAM, I agree that 512MB is more appropriate. I
doubt serious that you would see any difference between 512 and 1 GB.
Then again, there are times when I fill up the 640 MB in this old G3
Powerbook, and things start to slow down (Virtual PC is a real RAM
hog; add Word, a couple web browsers, Eudora, Adobe Acrobat, and
Photoshop, and you can use up 512 easily. Meanwhile my daughter is
not having any issues with her new G4 iBook that has just 256MB RAM.
Bottom line, it's just a question of what you plan to do with it.
Thanks for the feedback on this. I'm glad you are taking a closer
look. Also glad to hear you had some positive impressions of the OS.
Regards
Craig
P.S. Did you have any problems popping off the plastic cover to
install the RAM?
