Should I buy the Sony TX ultraportable or the heavier HP for daily carrying?

This is doubtful, as Aqua stores images of each window in memory (or video memory if you have enough of it). Most X11 servers do not do this, but unfortunately, things like Mozilla and Firefox like to store pixmaps in the X11 server.

Ohh I see Mr Unix is in the house. Welcome back Anyway Yes I guess you are right...

I think a full on install of KDE and Aqua would be about the same tho??
