Tough decision! I think.

I'm trying to choose between the new Sony Vaio

A good deal on a Toshiba A505

And A Toshiba Thin and Light

I'm a student so I'm out and about a good bit, so I'm just having a hard time deciding based on my little research. I like the Vaio best but I wonder if the thin and light is better fit for a student who doesn't game and will just use the HDMI for netflix and hulu. Also, the normal toshiba is a great deal and has good battery life like the thin and light but it looks huge. I just basically need to know if the Toshiba's will actually hold up whereas I know the Vaio probably will. HELP?
