From now, I will write posts about my journey in Ubuntu linux land whit my thinkpad X60s. I have been using it, for about five years, first with Windows xp then Windows 7 with an ssd. Firs I liked Win 7, but as time passed the system became more and more unstable and slow. I even installed Windows 8 for a few days, but I don't really like "metro" interface, and the whole OS became sluggish after a few hours of use.
So my "old" thinkpad looks like this:
X60s - spec
core duo 1.6
3 gb mem
csx 124 gb ssd
