Xite isn't released yet...
but as a rule of thumb you can pretty much consider any laptop for less than 3K Euro a piece of crap in one or the other way
all laptops notoriously suffer from heat problems
no laptops are designed and built with real-time audio processing in mind
well, I should not be that negative...
(imho) you may find what you need in the military and outdoor category... say Grid Computers (as an example for a supplier)
ok, enough kidding - but power and laptop
are opposites, unless you're willing to spend a lot of cash.
of course you can process audio on a laptop (thousand are doing it)
but for any given amount paid, you'd get the same performance for one third in a desktop - or for half the price in a rackmount.
with a laptop you better ignore performance completely and just enjoy the mobility
... though the peripherals (often) don't make it that 'handy' at all - it's not like taking it to a corporate presentation or so
