Have been running 10.04LTS from the CD only and like it. Have no intention of ever installing Ubuntu - former Freespire user driven to Ubuntu by the lack of ability to update Firefox in Freespire.
I want a system that accesses no drives unless I tell it to and saves absolutely nothing I have not seen and approved of.
Burned 11.04 and it seems to run, but it's useless to me if I cannot get to the older classic style - I don't want to learn how to drive again every year or so - that is one thing that drove me away from Windows.
For now, back to the 10.04 disk.
