High speed would be the current i7 machines but that wipes out the battery hours. And limiting the weight means we can't fit the big battery.
Same for cool. This removes the i7 based units. Try the i5 machines.
I'm looking for a laptop that would serve me well for physics research-related use: mainly running heavy mathematica and maple codes and C/Java-based data analysis programs (so I need a strong and fast processor). If it's a PC, it would have to work really well with a dual-boot linux/windows OS because most physics applications are made for a linux environment.
My other requirements is a screen size of 13-15 inches, weight no more than 5 lbs, ideally a long battery life (though not essential), and a computer that stays relatively cool while I'm using several applications and many internet windows at once.
The macbook pro would obviously be a great choice, but I'm looking to see whether there might be cheaper (under $1000) PC alternatives that would work just as well for my needs. Thanks!
