Desktop vs Laptop Question

[AZK]

Hey all,

I have an old desktop 1.0 gig, 256 RAM, that I am thinking of upgrading so that I can multitable without lag and just for general computing. I was looking at some of the dell configurations which look nice. I also recently purchased a Dell 700m for school/class, note taking, random poker on trips whatever. I never thought about using this brand new comp. for poker but I know a number of you have laptops that you multitable on...so I was curious who does what and why. After a few minutes of typing/mousing on laptop my hands kill and make me not want to use laptop as much as I probably should. I've never looked at a laptop as my 'main' computer, was always brought up with desktops so this is new for me. Plus, I've always had it in my mind that laptops are not as strong as desktops, so the idea of leaving it on 24/7 doesn't seem like a good idea, whereas I can't remember the last time I turned off my desktop, and I datamine with it, etc... So who uses desktop vs. laptop, and any other advice recommendations you might have on buying a new PC or just making a few modifications to outfit my laptop. Thanks.
