Ok, I may not know everything bout this computer but I do know that I REALLY like it. It's a small laptop, small enough for me and my lap isn't quite as long. It's not like those tiny tiny laptops that practically fit in the palm of your hand.This laptop is extremely lightweight to where I can carry it with one hand. The screen is no overly huge either. I like it. I believe it's a 15" screen. It has several memory card slots, I'm still trying to figure out all of them, but I know for sure it has a SD slot. It also had 4 usb ports. I don't know what I'll do with 4 usb ports but I'm glad I have them...
