New laptop on it's way
Finally, I ordered a new laptop. I should've done that a year ago. My (now 2,5 years old) acer has been crashing frequently since then.
The specs of the new one are great. It's a Dell XPS M1330, 2kg:
13,3" screen (1280x800)
Core 2 duo T7250 (2ghz, 800mhz fsb)
4gb 667mhz DDR2 SDRAM
Geforce 8400M 128mb video card
And a crappy 160gb disk, which I'm going to replace with my old 100gb 7200rpm hdd.
It cost me €970, which is a bargain. An apple with the same specs would cost 1400 euro orso.
