Windows Vista RC1 (build 5600, the one we didn’t get a chance to review..) is just great. It runs really fast, even faster than XP on this Centrino Duo with 2GB of memory. It’s stable (I haven’t restarted since installing it half a day ago, which for me is quite an accomplishment), and doesn’t require reboots even after installing core system drivers, such as the chipset, onboard SATA controllers, and audio devices, whether you use XP or Vista drivers, it just works.
Now that we’ve got that out of the way: Vista support for Pocket PC or Windows Mobile 5.0 devices is terrible. Very terrible. Some people were really happy back when Beta 2 got an update that fixed all aspects of Windows Mobile synchronization with Windows Vista, but guess what… it still doesn’t work.
