Vista works on the iXPS2... the only problem i have is my wireless network. But that's not so bad considering it's beta and Vista installed all the drivers automatically. I'm sure i can fix the wireless problem, i just haven't bothered.
Vista is VERY sweet. Very streamline, without things being bloated or cluttered. The 3D desktop is wild. Also, dpi scaling actually works, so if you increase the dpi, it scales correctly in all the windows. But what i'm most excited about is the new Windows Media Player and how it handles all your mp3s and videos... just sooooo sweet.
It's also got gadgets (ie konflabulator / OSX widgets)... but most of the gadgets in beta suck. Although i can see where MS is going with it. Gadgets, Live.com, hell all of Windows and MS products, seems like they're all being integrated with live.com. Your hotmail account is becoming part of live.com. So is msn messenger. Gadgets. So i think what they're trying to do, is free people from specific computers, and have people personalize themselves through live.com, and then live.com follows them wherever they go. For example, in order to get a gadget, you need to have it personalize in live.com... so if you go to another computer, and log in to live.com, all your gadgets could potentially load onto that computer for you. So if you have gadgets to check your mail, another gadget that shows your stocks, and another gadget that has a list of your tasks... if you go to another computer, and log in to live.com, all those gadgets would load for you as if it was your main computer.
Anyways, that's all my theory at least. But i'm glad Vista is coming out. 'Don't fix it because it ain't broken' is a dumb philosophy to live by. It's about time a new OS is coming out, one that's taking advantage of all the computer power and bandwidth we have now.
