Needed a fast laptop... This one provides speed!It's fairly large, but that's fine with me. I am still able to carry it around in my backpack with ease.It has a small thing that sticks out of the laptop on the back, a long round thing that sticks out about a half an inch, I did not know this was going to be there, but I am not bothered by it... I don't know much about computers, so I don't know what it's called, and I know its not unusual. I don't know if it's part of the battery or not, but I've seen it in laptops before...So far, it has been a major blessing for me, I can not complain at all.
