Until Sony overhauls the design of its UX series of micro PCs to make telling them apart a bit easier, I hope the following chart (last updated 03.27.08) will help to keep everything straight.

Ux_colors

I’ve tried to make the chart as accurate and complete as possible by cross-checking with Sony press releases and product pages, but it’s still a work in progress.

Similarities

The Vista models are said to have a slightly different keyboard, but otherwise all of the units are aesthetically identical. They all measure 5.91”(W) x 3.74”(H) x 1.27-1.50”(D) and feature a 4.5" SVGA (1024 x 600) touch screen, USB 2.0 port, DC-in, port replicator connector, headphone and microphone jacks, Memory Stick DUO slot, biometric fingerprint sensor, front (1.3 MP) and rear (0.3 MP) cameras, Bluetooth, and Wi-Fi (802.11b/g).

Differences

In addition to the specs listed below:

  • All U.S. models have integrated WWAN (Cingular EDGE).
  • All other models have a Compact Flash slot.
  • All Japanese models (except the UX50) also have a 1Seg TV tuner and/or FeliCa card slot.
  • Core 2 Solo Vista models have 251MB of video RAM, Core Solo Vista models have 224MB, and all XP models have 128MB.

Solid state drives (SSDs) are indicated in bold.

*The Japanese models are confusing because of the "VAIO Owner Made" service, which allows customers to mix and match a number of components. This, on its own, is fine, as many companies offer their computers in made-to-order configurations. The problem is that Sony Japan adds letters to the model numbers that don’t always correspond to anything significant. For example, the UX91S and UX91NS, which make up the UX91 series, are both available with an identical set of customizable options (HDD or SSD, CPU, OS). Thus, they are essentially the same unit. The UX90 series is similarly problematic, as the UX90S, UX90PS, and UX90SSD are often used interchangeably.
