It's time to replace the pos that I'm using, so any suggestions/comments? I've been looking around and found the following laptops that look good.

Vostro 3500
Asus A52F-XE2
Acer Aspire As5741-3541
ThinkPad Edge 0310
If you find the Acer over $100 less than the Asus K53, get the Acer. 4GB DDR3 ram is good enough and I would replace the hard drive with a 7200RPM one, which is essential for the better DAWS (a 500GB 7200RPM HDD is about $60). If you ever want to upgrade the RAM, you can get a 4gb DDR3 one for about $40 (prices are dropping on them). That's my take at this anyway.
