Sony Vaio Laptops?

[J Flex 188]

From my media arts teachers recommendation and from my own impression, it looks like Sony VAIO computers and notebooks are one of the most reliable brands around. Currently ive got an offer for a sony vaio PCGFRV35 http://www.sonystyle.ca/commerce/ser...09n32160n32162 laptop (P4 2.66GHz, 40 gig HD, 512 mb RAM) sitting for 2081 Canadian. The MSRP off of the sonystyle.ca website is 2199 (read 2200). Im planning to make use of this for light video editing, i.e. uploading and editing while at regionals, and then compiling everything on my desktop but also for general school work etc, especially in the next couple of years when i get to university. The only qualm i have is its 64 MB of shared video memory.. i dont plan to play many games on it, but im just wondering what the system performance would be like when running something like Adobe Premiere?

There's also a Sony V505H thats around 200 dollars more with a centrino based processor, but im not sure if its worth that much.

There is also a system im looking @ from directpc.ca.. mostly customized to around the same specs, with not-well-known manufacturer, but a better video card. for 2050.

My question would be are the Sony VAIO's the best choice for this type of operation? i.e. Multimedia Editing with general specs.

Thanks CD readers =) i dont belong to any computer forums, so i figured this was good a place as any!
