You're going to buy an overpriced viao for .... as you say "Craptop" duty?
What does the usage entail, what do you do on it? Whats your pricing range?
Your link didn't work but currently its an old core2duo and amazon still has it up for about 1100. If you buy a C2D laptop for 1100 you deserve what you get. Also, according to reviews the battery life on those viao's is abysmal.

Mobility and Raw Power: Thinkpad edge

Im not a lenovo fanboy, they just have 2 nice products at those price ranges, I really like HP's offering against the x120 which the dm1z but you need to get it from their site instead of newegg.
You listed a 16 laptop for "mobile" duty. It depends how "mobile" it is. I have a 17 in asus which is not a mobile pc by any definition.. it gets moved from place to place but i dont use it while on a train or a plane, its just too big. Anything bigger than a 14 or a 15 is going to give you some grief if you are trying to use it like that which is why i showed 2 different 11-12 inch options.
If youve got a different use case scenario let us know.
PS if you are deadset on a viao, at least get an up to date one:
