I have a sony Vaio is fine as a pc but the right hinge has broke in less than 2 years not good from sony at all, now held on with tape
I bought it mail order and wasnt to happy with it when it came for build quality, my advice is to try it our for feel at a shop even if u buy mail order.
nice choice just one point, from my limited knowledge, is that if youre wanting any mobility, go for a centrino rather than the P4 CPU. Battery life will be much better.
