I've been using the Windows 8 preview on my desktop for a little while right now, and I've been wondering both who else has been giving it a try as well as what you think about it so far.
Personally, I find that it's a bit of a mixed bag: it's clean and slick, with Metro, and I've always liked Metro on WP7 and the latest Xbox dashboard... but I'm still finding that the transition to the desktop PC isn't 100% smooth. To be honest, Metro looks nice, but feels a bit awkward in this iteration. I'm also not really liking the disconnect between the Metro portion of the OS and the traditional desktop portion of Windows 8, even though I love that you can switch between Metro and a sort of legacy mode as well.
On the whole topic of disconnect, if I'm on IE and browsing the web, but then I want to have multiple windows open? Well, if you want 2 apps open, you're fine... otherwise, you switch to desktop mode and reopen IE... which doesn't exactly pick-up where you left off. Multitasking is possible in Metro, but you can only have TWO (2) apps on screen at any one time. Even then, you have your prominently displayed app that you're working in/on and the other is smooshed to the side and pretty much unusable and not visible.
Even on the legacy side, they've done things like take the start menu completely away. So, navigating becomes a convoluted mess, unless you were to slap an icon for everything on the desktop... or you feel like digging through Windows Explorer, just like the good old days.
To me, this feels like Windows Mobile all over again, except where they're trying to take a great mobile OS and force it onto the desktop, as opposed to building a mobile OS out of a good desktop one. They're essentially trying to jam a square peg in a round hole... again... And, at the end of the day, I could see a Windows 8 tablet in my future, but not so sure I could ever really enjoy this experience on the desktop.
I do recognize, at the end of the day, that this is pretty much just a BETA, however. Ultimately, we'll see what the final release ends up bringing to the table.
Maybe they can add in a third mode: DOS!
