I'm currently on a very capable but aging laptop (Toshiba Satellite with dual 1.73GHz Intel processors, 4GB RAM, 160GB HDD, Win Vista, etc)...but, it's nearly 5 years old and things keep dying on it (battery, hard drive, charger, now it has a weird thing where if you bump the table it's on hard enough, it'll shut the computer down...loose wire somewhere I'm guessing).
So, I'm thinking of picking up another laptop and selling this one while it's still worth a couple hundred bucks.
I mostly do internet, watch lots of movies on it and photoshop (some of my stitch files are massive, 500 MB+)
What processor should I look for? Dual core? Single? Brands to avoid? Look for? (I'm thinking of a Toshiba with 4GB of RAM) but can't decide whether to go with a single core i3 or a dual core Athalon, etc...HELP ME 
Thanks,
Tamas

Let me know how it works out once you get to put it through its paces!
