So, I'm basically liking Windows 7. Take everyone's advice and skip Vista. Of course go to http://www.howtogeek.com/howto/windows-vista/disable-caps-lock-key-in-windows-vista/ and disable the stupid CAPS LOCK key. When I needed to add a HP LaserJet 1020 attached to a Mac Mini, I needed to download the "Adobe Universal Postscript Printer Driver" and specify "Generic Postscript Printer" and "http://192.168.1.100:631/printers/HP_LaserJet_1020". Also, Adobe's reader didn't do a good job of printing a pdf to that printer, but foxit it did. Strange.
I'd love to hear the logic behind not being able to do an upgrade from XP to W7 without saving all one's files and doing a clean install.
