I'm faced with a pending clean install due to a dying hard drive in my old Dell Inspiron 8600 laptop. I've been running Ubuntu 8.04 on it since... 8.04 and I've been more or less happy with it except that it's a PITA to recompile the kernel or do any other kernel related work. I mostly do software dev on it, gcc, gvim, c/c++/perl/php/mysql and running vmware server 2.0.
I've heard mixed reviews of 10.04, and am wondering what to put on the new HD. I'm even considering just sticking with 8.04 as it seems to mostly meet my needs.
