The company I work for is going to buy me a new laptop before the end of the year. Right now I use Ubuntu 11.04 on a ~3.5 year old Dell Vostro 1700. It's a dual boot install and it runs good enough, but it's not perfect. I attribute most problems I experience to the age/wear of the laptop, not Ubuntu.
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'm looking at a Dell Precision M6600 and also at a MacBook Pro 17-inch. Work is paying for the machine, so thankfully price is not a concern. I just want Ubuntu to run flawlessly. I use Ubuntu because it makes me so much more efficient at my job (web development, etc.). I don't customize the OS much and I'm not messing around too much behind the scenes. I just want Ubuntu to run as smoothly and reliably as possible.
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?
Note: I have only been using Linux regularly for under a year. My knowledge of video cards, chips and other hardware and specs (and how they relate to Ubuntu) is somewhat limited.
