I must be old fashioned as I have never used a laptop throughout my time as a PhD student. I just used a PC, and only Linux OS (Ubuntu and scientific Linux). But I imagine that any average priced laptop would do the job for most PhD, I would not recommend a mac, for one it is too expensive, and if you want a free alternative to mac os then just use Ubuntu on a pc/laptop :D
