Need help finding best laptop

I'm planning on getting a new laptop/netbook and I want something that's very portable so i can carry it to school everyday on top of all my books. If anyone could help me narrow down my search it would be much appreciated.

1. Screen Size: 11.6 - 13.3 (preferably 12.1 but any of these work.)

2. Budget: Around $500 but obviously as cheap as possible.

3. CPU: At least a duel core. A single core wont cut it for my needs.

4. Specific Needs: Of course I will be doing day to day tasks such as: Web surfing, typing papers/homework/notes, and watching videos; however, I want to be able to play some games. The highest demand game i will most likely play will be Guild Wars 2 when it comes out. HDMI is a want also because i want the ability to output good quality 720p videos to TVs.

5. Preferred Dealer: Newegg or Amazon.


The main laptops/netbooks I'm looking at right now are the Acer Aspire AS1551-4755 and the ASUS Eee PC Seashell 1215N and I am leaning towards the 1215n.

Also I would like the know which GPU is better the Ion 2 or the AMD 4225.

Thank you.
