I've been forced to play with Ubuntu Linux recently, although not for development -- yet.
Its much more stable with 6 GB of RAM instead of 4. Unrelenting hang with live CD MEM @ 4 GB. Occaisional loss of mouse - fixible with the terminal. Flash is required, but support has been dropped. No alternative to Acrobat Pro as far as I know.
Adobe appears to be at war with Linux.
I don't know how to scan. I haven't managed to print the URL when printing, but still running LIVE cd. I have yet to manage to install it on an SSD. No solution for USB device servers.
Supposedly an EProm burner I got will work under WINE.
