Like what? Personally, I think the form-factor of a tablet is next to useless, and I'll stick with laptops and desktops,
You might be the only one, these days. In the beginning of the tablet thing, I would have agreed with you... but now my Nexus 7 gets almost as much time as my beastly desktop. My desktop reigns supreme for actual work and gaming (Android/iOS games suck, as a rule), while my Nexus 7 is for sitting on the patio with a cup of coffee while checking my email/news. The Nexus also spends a fair amount of time in the kitchen for recipes, in the living room for quick Googling, etc... I'm not going to use it for editing photos, transcoding video, coding, or typing anything about 200 characters, though.
Now if my tablet could run full-blown Windows, at a good speed (better than a shitty unpowered Windows Starter-only netbook) it would be a very nice thing. Then, for instance, I could have done some basic Lightroom work on my recent trip (the screen would still suck compared to my large wide-gamut IPS panel). My girlfriends Netbook can barely run Picasa, so its flat out. My old 14" laptop could do it, but it is another fairly heavy thing to carry around... A 10" Windows tablet would be perfect.
Hell having a tablet/phone with an OS that doesn't feel like a damn toy would be nice... I'm not just talking about Windows, having full blown whatever distro you want would be awesome. Especially if they were cheaper than Windows 8. And Ubuntu x86 tablet would be perfect. Hell, better, since it could be tailored to hardware (Like iOS or tablet Windows), avoiding Linux driver hell.
But then again, I'd own the Windows 8 tablet (not RT) right now, but for the fact that it is horribly expensive. $1000 for a convenience item is stretching it, especially when it is hardly as convenient as anything else on the market... It weighs two pounds, and has some unimpressive battery life. Fix that, drop the price by half, and then we'll talk.
