Because of the buggy way that Elementary OS Luna locked up my wife's nc6400 I've loaded Ubuntu 12.04LTS onto her laptop for easy of use and gone back to Mint 15 MATE for my nc6400 since I do a bit more "power" stuff then she does and can use the extra stuff that the Mint 15 Op System has.
Elementary OS Luna looked pretty nice but I just can't deal with an OS that's going to be picky about which hardware it's on. Anyway, that's my story and I'm stickin' to it. LOL
