i haven’t had a single crash with win 7 after running it 10 months. i have had 2 or 3 freezes, but i have attributed that to hw issues (maybe incorrectly, i don’t know).
i do know that for the mountain of money i save buying hw and sw that is much much cheaper than apple or linux counterparts, i can put up with a few more problems and i’m not sure i even have more problems at this point. that’s just me.
i don’t use external usbs due to sw crashes but due to hard drive failures, which are much more devastating.
