I'm also dabbling with various Linux Os's. I'm using Ubuntu 11.10 on an old laptop(Dell Inspiron 1100 1gig memory, 2.8Mhz processor. I also have Linux Mint which I do like their desktop better but whenever I install the upgrades
it locks up my laptop.
It's going to take a lot of strong arming to get me away from Win7 though. I'm finding the learning curve is easier with Windows than with Linux OS's.
