Quote from mikasa:
simple, having a deeply intellectual mind
That's why you care about booting times and such.

There is no reason why one should boot more than once max. a day. Again, as long as the performance is better (gaming and trade execution) why the fuck your intellectual mind cares what's going under the hood?
Not to mention a real trader would have 2 computers, 1 dedicated for trading (XP is just fine) and one for gaming/porn/entertainment/whatever.
