Thanks for sharing that, I didn't know about the defragment thing that makes my life much easier. Interestly I was wondering that about the other day as my laptops been lagging, think its more due to the chip than the version. which version of linux were you using at the time?
<my2¢>I used Fedora 8 thru 11 (Werewolf to Leonidas). Fedora was my first full-time, make-the-leap-to-Linux-only distro (WinXP started BSODing my workstation - I used Fedora to recover and ended up totally replacing XP with Fedora after rescuing my files). The main differences you will experience in Fedora-land is the total FOSSness and a need to learn more about SELinux than you probably ever imagined wanting to know. Anything not-FOSS, you will need to install and configure yourself (with help from kind strangers in forums on the wild-'n'-wacky-web). Unless your primary goal is learning a huge amount of stuff totally unrelated to coding for the Interwebz, and you don't especially cherish ease-of-use for non-FOSS programs, give Fedora a pass.</my2¢>
