I can't comment on the HP Elite, or the newest MacBook Pro's, but I run X2 on my bootcamped
2011 macbook with no problems at all. You might want to factor in a 7200rpm hd though,
the standard 5400 drives are pretty useless for audio work under bootcamp.
There is the option to replace the DVD drive with a second HD for audio, and use a usb
DVD drive instead, but this could raise portability issues.
But generally, yeah, everything runs smoothly here.
Of course, I'm sure there are others that have had nothing but hell with it h'ha
