If the model numbers to Sony’s VAIO TZ series sound confusing, we’ve thrown together a short guide explaining everything.
A brief summary:
1) They either ship with 1GB or 2GB of memory
2) There are two CPUs: Intel Core 2 Duo U7500 (1.06GHz) or U7600 (1.2GHz)
3) There are four colors: Black (Classic Black), Champagne, Bordeaux Red, and Premium Black.
4) They either ship with 100GB mechanical hard drives, or 32GB Solid State Drives
Keep in mind this is for the United States/North America. It does not cover the Asian/Japanese versions of the Sony TZ series.
