PS3 or laptop?

[The Phoenix]

I would not go with that machine, due to the limited Intel HD 4000 graphics card.
Try & get a Laptop rather than a Notebook, with a independent graphics card in there, preferably Nvidia, due to there rapid driver updates & they seem to work far better than the ATI/AMD cards. (As noted on these forums).
The processor was great a i5 is extremely powerful, and a great choice.

But in the end is up to you, how much you are willing to spend, save up for the best machine you can possibly afford, that way it will last far longer.
