[Sergey_Z]

Three weeks ago I've bought one VGN-SZ3XP/C laptop.
There are many other VGN-SZ series in the shop now.
I've readed the description of new Sony Vaio VGN-SZ5XWN/C, and didn't found the difference
between theese model and my (but the difference in Windows versions).
So, is enybody knows, what is the difference between all of theese SZ2,SZ3,SZ4,SZ5 notebook versions?
Best Regards,
Sergey.

The higher the number the newer the notebook. Sony release a new model every 3 months or so. The models are not dissimilar so other than the resent change to Vista there is little to choose between them really. Fairly soon you will see a SZ6...

Being a bit ironic here but the price tag
