Could you tell me how yu carry your 17 inch Vaio ?
I tried different models from Sony, Case Logic, etc...but none has the perfect size !
Thanks for your ideas and suggestions
Here are all the compatible accessories for your VAIO.
I personally use backpacks as they look less like they are carrying something expensive thus are less likely to be taken over a standard laptop case. This will also make it easier to carry as its not the lightest of machines.

I like techair, plus they're trackable.
I carry mine with a small crane.
Only kidding - the Backpack is very good.

I bought a Targus XL Computer Case, and it's very nice, but honestly, I do not move my Vaio very often :smileyblush:
