Sony Vaio U101
Sony produced an impressive amount of ultra portable devices.
The Vaio U101 is yet another from the UMPC series, available in Japan only, offering incredibly small portability for it’s time.
The Sony U series was well renowned for being amongst the smallest independent computing devices, forming the so-called Ultra Mobile PCs (UMPC) category.
Before the netbooks appeared during the mid-2000s, the Sony UMPC avant garde set the tone for ultra mobile computing for several years.
Despite rather hefty pricing, Sony delivered innovative concepts and was not shy in trying out even new approaches and form factors with this series.
While the U101, much like the U1/U3, follow a familiar look of shrinked down laptops, the U50 und U70 series went more into directions of handheld and tablet style PCs.
A commonality for some of the earlier Sonya UMPC was, that they did away with Intel CPUs in some models, and incorporated the Transmeta Crusoe instead. The Crusoe, not being a native x86 CPU, implemented the x86 compatibility using code morphing, which, as one might guess, was propably not the best from a speed-wise perspective when compared to native x86 CPUs. However, the Cruoes was adept for low power consumption, which at the time, was in fact a big deal.
It would still take a while for power efficient Intel CPUs to appear. In 2003, the later U series models saw the transition to Intel Celeron M/Pentium M CPUs with clock speeds up to 1.1 GHz.
The U101 sports a Celeron at 600 MHz, with 256 MiB RAM and a 30 GiB hard drive, a typical setup for the time. The 7.1″ LCD features up to 1024×768 resolution. Overall, a very leightweight device already at 880g and a dimension of 178x139x34 milimeters, and a foreshadowing to later Netbook-style devices. All in all, a good companion for computing on the go, to which the built-in WiFi and Ethernet options greatly contributed.
One special thing about the U101 is it’s pointing device. Rather than using a trackpad or a trackpoint in the usual positions below or in the keyboard center, it features a thumb-controllable trackpoint and mouse buttons in the upper right corner, just beneath the display hinges.
On the upper left-hand corner, a similar control pad was available, from which different functions, i.e. for multimedia, can be accessed.
Combined the fact that the display can be moved within a 180 degree angle, this allowed U101 to be held and used like a handheld gaming consoles.
The PHINTAGE Collection currently holds a VAIO PCG-U101.
