A disclaimer: I never liked Windows 7, or Vista, or XP. I used them, but never enjoyed the experience. Windows Phone and Windows 8, and then 8.1 are the first OS Microsoft ever made that I liked. I fact I loved 8/8.1. I installed the Windows 10 Technical Preview on my Surface Pro. I'm not loving it so far. I feel like its a huge retrograde step so far. A lot of what made Windows 8/8.1 great on a touchscreen has been either compromised, or completely removed. Where's the touch IE? I can no longer swipe up to access app functions. Instead I have to try to hit a tiny button in the app title bar. Or resort to either my pen, or a mouse. I can't dismiss apps with a swipe either. Now I'm aware they're going to add lots of stuff to this early preview. But as it stands right now, its a disaster for Windows tablet users. I'm buying a new computer in February. I sure hope they've improved this by then. I was strongly considering getting a Surface Pro 3. Now I'm totally second guessing that. If I was going to the store today, right now, to get that new system I'd probably get a cheap laptop and a 128GB IPad instead. And I despise iOS. But, its TOUCH FRIENDLY.
