Drivers have flowed quite easily for most of my hardware. The only company dragging their feet in my case is Creative, but that's nothing new. They must only hire programmers who have successfully finished reading Visual Basic for Dummies. Fortunately, someone's modded the Vista drivers to work perfectly with Win 7.
My ATI card is fine (even though I have an older card that has to use the legacy drivers. Bah!) and my Intel NIC is a dream. The Intel Win 7 drivers are giving me better performance than I got under Vista. Probably due to all that auto-adjusting networking stuff that never was quite right in Vista.
Windows 7 is coming and it's just a little over a month away. Companies really don't have any excuse not to either have their drivers released or near release. Windows 7's driver model is not that much different than Vista's so there's not the excuse available there was when people were transitioning from XP to Vista.
As little Kylie says in the new Windows 7 commercial: I'm a PC and more happy is coming.
Windows 7 is snappy and 'reponisive'.
