I just can't believe how bad Windows 8 is! Sure, like most I always thought it was probably a bad idea to mix tablet and laptop functionality, blah, blah, blah, but I had never actually tried to use it. That is, until my brother in-law bought his parents a Windows 8.1 laptop and my wife and I became their help desk.
It's an unfinished product! It reminds me of Windows Mobile 6.5 - a thin coat of touch-sensitive paint on all the same old stuff. Drill down past the top layer of settings and you're back in Control Panel applets. Certain web sites force IE into desktop mode because the new GUI doesn't support everything, and the Deaktop IE looks completely different. Half of the GUI controls don't provide mouse-over help. The mail client doesn't support gmail (more of a policy decision, I guess). I can't believe they bet their future on this, and I feel sorry for the engineers losing their jobs because of it - they didn't make this call.
I was shocked when I saw a desktop operating system for a touchscreen. All I can ever think of is Steve-O's comments about touch surfaces wanting to be flat. (IIRC, it was in the original iPad announcement, but I might be mistaken.) Boy was he right! I recently bought a little BT keyboard cover for my iPad mini (way cheep like <$20) and it is almost wholly useless. It's the worst of both worlds. If you need a laptop, get a laptop (love my MBA); if you want a desktop, get a desktop, get a desktop. Human psychology and interaction is *way* more important than saving a few bucks.
Even at Apple new prices, these optimized devices for completing tasks is the way to go. You buy the tool for the job, not bastardize tools to be all in ones. With the integration of OSX and iOS coming, I don't see MS being anyhow relevant in making tools for anyone.
