And it makes sense that they would want some continuity between different devices using their windows OS given the move toward tablets and smart phones among the general public. My complaint was that the execution was poor in Windows 8. I never minded the full-screen start menu, although not having a visible button to activate it in 8.0 was a mistake they shouldn't have had to correct in 8.1. I use my windows key on my keyboard, but the Start Button is a convention that has been ingrained in people since Windows 95. Leaving it out of 8.0 was dumb. What did bother me was that running Modern UI apps transported you to Metro-land, and left you feeling kind of stranded once you got there. Microsoft did a bad job of integrating the Modern UI stuff with everything else. And by default, some metro apps were associated with common tasks like picture viewing... so you're sitting at your familiar desktop, you attempt to open a JPG file, and you're booted to a full-screen environment tailored for tablet use. Try to listen to music, and you're sent to XBOX Music or whatever it's called, instead of Windows Media Player. Of course you can change the default applications back to their Windows 7 defaults, but it's something you have to frig with... and something a novice user might not understand. Anyway, once you correct those things, it's fine. It's not like Vista where driver compatibility was terrible and performance was just as bad. The core of the OS is fast, stable, and solid. Windows 10 allowing you to run Modern UI apps in a window on the desktop is a significant step in the right direction.
