Ok, so I haven't totally ditched Windows 7...but considering how few problems I have had and the fact that I have been running it for quite some time on my home computer, I decided to start playing around with the new Ubuntu 9.10 Beta release on my work laptop.
Thus far, everything is going very smootly. Running Ubuntu 9.10 32-bit on my Dell E6400 laptop and about 30 minutes into it, the box is installed, patched, sound, Nvidia video and broadcom wireless is working. My IRC clients are setup, my Instant Messengers configured, my plug-ins for Firefox installed, video codecs and flash player installed. Movies are playing in VLC, MP3's play, I'm connected to my Windows shares. All of this without any cdkeys or activation. You gotta love that.
I know that most of us are die-hard Windows fanatics, but I know we have some Linux fans here as well. It's good stuff.
