After first remarking that this roundness aspect should not be seen as something that's inevitably on its way to Haiku's future looks, I'd also (like Humdinger) say: keep it limited to the tab and more specifically the right side of it. From the screenshots you can see that a rounded left side in a tab doesn't combine well with the tab's 'inner square' that we use to close a window (this square now looks awkwardly "cramped"). Humdinger took the words out of my mouth when referring to Stack-and-Tile, which calls for squareness to give the most visually satisfying window-mergers (100% contact). Interestingly, by contrast it is roundness on the right side of a tab that can visually improve the stack and tile experience (also sharply remarked by Humdinger). With this argument, I'd say it would be a good idea make some mockups with tabs like this in a stacked situation. These could then also serve to determine the ideal radius by trial and "error". I've read somebody's concerns somewhere recently about the way Windows created rounded tabs: apparently this is done by just using a square corner and making a few pixels of it transparent, which can sometimes show up black when windows are loaded. Unless there is a way that doesn't produce visual glitches, the rounded corner idea should be ditched. But there's no doubt it can be done properly (Haiku style). As for the "fat" border alternative: it looks too heavy to me and not in sync with the rest of the Haiku experience. It just takes away lots of elegance. The concept fits round corners, but doesn't fit square corners. The 'grippy' (area in the lower right hand corner that lets you resize a window) is missing/overlooked (also previously remarked). I also don't see how the window called 'xData' could be dragged around in any other way than using the tab, so that would be a regression from the present situation. There seem to be scrollbars but those are for another use. There's less clear visual oversight in presenting the 'Menu', 'Window', 'Applications' and 'Clock' areas and those words themselves now look cramped. The total looks more flat, maybe that's why N. Blachford came up with more prominent shadows. But by their size, those shadows kind of smudge the background, IMHO. Textures in Haiku look out of place...I believe that the freedom to personalize through Desktop background images plus the options already given in 'Appearances' gives the user enough room to create the atmosphere they like. Grey is neutral = good = serving = what a OS needs to be (and Haiku uses a very nice grey, BTW). Enough, Meanwhile P.S.
