Well, this was expected, but kudos to Microsoft for doing the right thing. It's a shame they're extending Home and not Professional though.
I have been playing with Vista (32 bit) for the last couple of weeks - my biggest gripe is the HUGE (and I mean exponentially H...U...G...E) waste of disc space. I installed a fresh version of Vista Home Premium (mainly because I got a free OEM copy) and updated it from Windows update - by the time it was complete it had used 16Gb of hard disc space before installing any applications!
Vista using 16 GB of HDD space it's not good news, such requirements suggest the use of vLite to cut down the bloat.
If Adobe insist on 64-bit Vista I think they will find a huge group of people cross grading to the Mac. Who in their right mind would want to be forced to use Vista for PhotoShop ?
Er, only the 64-bit edition of Photoshop CS4 requires Vista, AFAIK there will be a 32-bit version. BTW, Mac is not getting a 64-bit version, so I'm afraid people will cross grade to Vista from the Mac using Boot Camp, now that's funny
