On the powerbooks there was a softpoint near the power coupling. Apple always has great screen resolutions but their hardware ALWAYS seems to have some horrible flaw. I also had the 1,2 17' MBP (read really early edition) and a couple of powerbooks before. I've run both the 17' 5,2 Macbook Pro and now the M4600 Dell. My knowledge of video cards, chips and other hardware and specs (and how they relate to Ubuntu) is somewhat limited. Note: I have only been using Linux regularly for under a year. Is one of these two machines - Dell M6600 or MacBook Pro 17' - better suited for Ubuntu than the other? If I'm not using Windows or OS X that comes w/ the machine am I losing a lot of the performance gains from the hardware, or can Ubuntu take full advantage of all the specs? I just want Ubuntu to run as smoothly and reliably as possible. I don't customize the OS much and I'm not messing around too much behind the scenes. I use Ubuntu because it makes me so much more efficient at my job (web development, etc.). Work is paying for the machine, so thankfully price is not a concern. I'm looking at a Dell Precision M6600 and also at a MacBook Pro 17-inch. I'm going to do a full install on whatever laptop I buy next, so no Windows or OS X at all, only Ubuntu. I attribute most problems I experience to the age/wear of the laptop, not Ubuntu. It's a dual boot install and it runs good enough, but it's not perfect. Right now I use Ubuntu 11.04 on a ~3.5 year old Dell Vostro 1700.

The company I work for is going to buy me a new laptop before the end of the year.
