I recently installed Ubuntu on my Inspiron 1420 with a 1.8gHz C2D and 2gB DDR2. I must say, I am loving it. I dont think I will boot into my Vista partition again except to use windows specific software. Not only is Ubuntu more aesthetically pleasing because I didnt feel like paying out the ass for Vista Ultimate, but my battery life is greatly increased because I am using less than half as much memory performance and nearly a third the processing power for the same tasks. I dont have bothersome notifications and no need to suck system resources with antivirus programs. I love the fact that it automatically dims the screen when I step away from the computer to conserve power as well. I am running all of the asthetic features with onboard video (my laptop has no daughter card) and there is no lag or jerkiness. Overall, if you mostly do word processing, internet surfing, pictures, video, and music then you may want to check out ubuntu. You can look up to find out if it is compatible with your chipset. If you cant find out if it is you can still download it and burn it and boot it as a live CD and see if it will work with you chipset. The Ubuntu install includes a partition editor so you can install it with out any harm to your existing data. I gave my Ubuntu boot partition 2gB which is a drop in the bucket for my 160gB HD. Hell, dell took away 2gB of my hard drive to put their media direct bullshit that nearly no one uses on my laptop.
