I installed 7.10 to dual boot with Xandros 4.0. Live CD worked great to partition HD and install was smooth. However, on reboot, GRUB did not show the Xandros partition. Fixed by using live GpartEd at boot and now use LILO as boot manager as it correctly recognises all partitions and OS.
Printer was a challenge, but resolved. Still can't connect to internet. The Xandros Network Connection wizard is far easier, more effective and intuitive to ex Microsoft exiles.
Gnome Eye much better for seeing photographs on the system than is the Xandros equivalent. Stoked to have Gimp 2.4!
