The only thing I can comment about this is that the other day, when I was in BB checking this very laptop out, I decided to compare it to a dual core TL-50 model they had nearby. I basically gave it 4 tasks to perform, and did the same with the dual core laptop. O/S, ram & hard drive was the same on both machines, but while the dual core machine easily handled the tasks all at the same time, without pause, the MK-36 single core machine flat out FROZE! Now I realize that the comparison between a single core and a dual core processor is hardly fair at all, but the tasks I gave the machines are some that my old XP2800+ machine (that I'm using right now) could handle all at once, without a problem. Granted, my computer isn't running the memory hog that Vista is, but XP was considered a memory hog too, at one time, for those that remember.
That being said, if I did decide to buy that machine, I'd likely look into eventually upgrading the cpu to dual core, and adding another gigabyte of ram to it. And that would raise the price (eventually) to the price of a dual core notebook anyways.......so why not just buy one in the first place??
