exactly as aquilea_bk, except that Solitaire thing.
Thought of switching to Ubuntu but got really nasty help on the forum.
Completely switching to mac is not a deal due to the costs involved. Its too much of money for a machine that will not last for more than 3 years (due to technology or whatever other reason) I don't do any high end computation that I need such a powerful machine. Similar spec windows machines cost pretty less.
Only hassle is maintenance of windows machine, but I am ready to accept that hassle for costs and as a grad student, you don't have much money, do you? (Apple is not that cheap in Europe for students, for academic institutions, no VAT but not for students)
At the end, do you manage to get your job done? yes, move on..
