I had made a post about this a few weeks ago also (about purchasing a Mac, no directly related to vulnerabilities). The main reason being that my laptop died and I figured it was time for a new one anyway. The MacBook seems fairly appealing for the reason you've suggested; I can run all 3 on one. I've still not yet made any decision (I've just been using my work laptop more instead), but I'm curious to see if anyone does make the move. There are definitely some anti-Apple(/Steve Jobs) people here so watch for replies
