Sony VAIO Z Series Notebook Model Numbers

The Sony VAIO Z series laptop is one of the best laptops ever made:

  • absolutely gorgeous screen (one of the best laptop screens I’ve ever seen)
    • LED based backlight
    • excellent color gamut
    • bright and saturated like a glossy screen but NON-REFLECTIVE like a matte screen!!!
    • durable screen (with a protective coating)
    • decent resolution options
  • lightweight
  • powerful (dual core, 2GHz+)
  • plenty of storage (can support dual SSDs, HD, or potentially a combination)
  • upgradeable (memory, CPU, storage, [but you void the warranty with the last two]
  • stylish
  • somewhat reasonably priced (especially if refurbished or on sale)

However, Sony has a convoluted naming scheme. The model numbers are all VGN-Z999 where[999] is a three digit number, sometimes followed by more letters. It makes it very difficult to search for Z series laptops on eBay and other places like that. So here, for reference, is a partial list of VAIO Z series model numbers with some descriptions:
