This machine is a workhorse, and you can get it in desktop-replacement-friendly sizes (mine has a 17-inch screen!).
The downside is, of course, that the bigger it is, the MORE it WEIGHS. I'm not gonna lie: by the time you pack the computer AND the chunky battery pack, you are going to be lugging that thing around, wondering why it's considered a "portable" computer!
It also runs hot, of course -- the power box is hot, and sometimes the bottom of the computer is super-hot, too.
That said, I've never met a laptop that didn't have these flaws. And this model has a lot going for it, too.
