First: I like Win 7. I am moving all machines to it and replacing older machines. Now the short version: I have Win 7 machines on a mix of Intel/AMD/desktop/laptop: I have yet to see one that will reliably complete the shutdown process if it has been in sleep mode for more than a few seconds. These are all high quality relatively new machines and a couple came preloaded with Win 7 so it is not an "upgrade" or older hardware issue. I have seen registry fixes posted on websites but these do not work. I have yet to see a Bluetooth enabled laptop that does not drop the connection to Microsoft's own Bluetooth mouse frequently when reactivated from sleep. I gave up using the bluetooth mouse on the laptop I most frequently use because of this. If Windows Explorer is not opened in a sufficiently large window the highlighted file selection will jump randomly to a different selection. I thought this was an aberration in the RC but it persists in the commercial release. CD/DVDs cannot be reliably ejected from any machine using the button on the drive, whether a newly burned disc or a commercial optical disc. Usually, but always, the software eject in Windows Explorer has to be used. In my experience this is a universal Win 7-64 annoyance. I cannot be the only user seeing these oddities in Microsoft's latest and greatest.
