Deepsix the Dell, and while you're at it, consider getting a desktop. Notebooks aren't fun to game with.
I have a laptop and all I use it for is it's mobility factor. I take it with me when I make a house call to fix a computer. It's also handy for grabbing directions when I have to find an address quickly.
Thing is though, these smart phones are capable of doing most of the things I need a mobile computer for and they cost way less. I'll more than likely sell the laptop and go with a smartphone in the near future.
