This computer is a delicate piece of crap.  I've had it for a month and the screen went haywire ... cracked internally ... i didn't impact it in any way ... and Dell is claiming it is not covered under warranty and then you have to deal with customer service hell  and wait 5-7 days and the cost is $200.  If this computer is not planted on your desk, ie, it has to move around, like in your padded computer bag, you run the risk of the screen cracking internally like happened to me.  What a piece of crap this thing is ... DO NOT BUY IT!!!!
