I think Windows 8 will grow on me, but for right now the Metro, ahem, new user interface makes tasks that used to be one or two clicks take three, four or even five clicks. It is clear that Microsoft designed Windows 8 with touchscreen interfaces being the primary target, and all others were secondary.
I have an iPad, an iPhone and an HP TouchPad (which dual boots Android and webOS), so I'm very familiar with and love touchscreens.
But I'm not going to throw away my awesome desktop with dual 23" 1080p monitors just because they don't support touch (unless it's my son planting his fingerprints on them just so he can watch me clean them again).
I can't help but wonder if Microsoft isn't being a bit careless, maybe even reckless, in this move. Windows 8 so heavily favors touchscreens that it would seem Microsoft is expecting touchscreen interfaces to completely, utterly and irrevocably obliterate, decimate, destroy, overtake, crush, splice, splay and accordian-pleat keyboard-and-mouse-based laptops and desktops, relegating them to antique computer museums.
I can use the iPad or TouchPad for a lot of things, but when I want to do a lot of typing or some heavy-duty work, please give me my keyboard and mouse.
