yea it wont be out for a while... and windows is now approaching vista kinda of like mac.. the gui interface.. with a more cleaner, sleaker, aqua type gui.. and yes the system resources are intense.. a MIN. of 512, 1GB if you really want vista to operate smoothly, a fast processor, a GOOD graphics card.. and im not sure what the other requirements are.. but it requires a very powerful machine.
vista is suppose to come out in a 3D windows interface.. meaning if you have seperate windows, you will see them in 3D.. and new side panel of gadgets.. a totally new GUI, special effects, icons, menus, etc..
i have tried beta 1, and gosh was it slow.. it was a celeron 2.7ghz, 512 ram, radeon 9250.. and it somewhat gave me slow motion menu-submenus...so if you have something similar to that setup of mines.. be warned.. then again, it was beta 1, so it my have its glitches.. and to top it off, i wasn't even using all of VISTA'S special effects....
it takes a lot of resources.. and everything will pretty much be redesigned as far as GUI. beta 2 is coming out around decmeber this year.. hope you guys are MSDN subscribers..
