After installing several builds of Vista/Longhorn over the past couple of years, I would really have to say the have pulled it together very well for Beta 2.

Previous builds had frequent explorer crashes, DWM leaks etc, and would be nearly unusable for any amount of time on my Acer x64 Laptop with 1.5 Gb of RAM!

Not with Beta 2 however, from install it had all drivers and runs almost everything I have tried.

Blue Screens/Lock ups/Driver issues 0

Did I just get lucky and pick a laptop that someone in Microsoft uses or what?!

Have many other Beta 2 users that have actually used a few different CTP's / Pre-CTP builds found this to be a vast improvement with regard to stability and speed - all I keep hearing about is 'blah this and blah that'...

not that its without its 'unfinished' bits, but overall I finally have faith in what will be the finished product.

I just hope that other Beta testers (I know Spoofnozzle has plenty of gripes) manage to see it running like it has been for me.
