There was a total of three models in the PCG-U lineup. The PCG-U1 and U3 both share the same design, apart from the fact that the U1 is white and the U3 is black.

However, while being not very fast, Transmeta CPUs were very power-efficient. While corresponding x86 CPUs could consume up to 35W of power under full load, the TM5800's power draw under full load was only 8.5W. The Transmeta CPU consumed even less power during tasks with medium to high intensity, like DVD playback (around 1.5W). This caused the U1 and U3 to work for around 3 hours on standard small battery pack and up to 12 hours on optional large battery pack. | However, while being not very fast, Transmeta CPUs were very power-efficient.

Overview
The Sony VAIO PCG-U was a line of ultraportable subnotebooks sold by Sony from October 2002 to circa May 2004. It could be said that PCG-U lineup inherited the form factor, concept and looks of the PCG-GT line to some extent. All models in the line were never officially sold outside Japan.
The first model, PCG-U1, was officially released in April 2002. The higher-spec model, PCG-U3, was released in October of the same year. The final model, PCG-U101, was released in May of 2003, shifting from Transmeta to Intel platform and featuring a transflective screen.
All PCG-U models had a ThumbPhrase feature, allowing one to easily type Japanese characters with one hand.
Despite the PCG-U1 and PCG-U3 both having considerably higher clock speeds than the PCG-U101, they are both far, far slower than the PCG-U101. The Intel Celeron M is able to be way faster in all usage scenarios due to being an actual x86 CPU instead of a VLIW (Very Long Instruction Word) one, like the Transmeta Crusoe.
The lineup was superseded by the completely redesigned VGN-U in May of 2004.
Detailed Specs
There was a total of three models in the PCG-U lineup. The PCG-U1 and U3 both share the same design, apart from the fact that the U1 is white and the U3 is black. The U3 was just an upgraded higher-specced and visually revised U1 with a faster CPU and more RAM.
One of the most interesting things about the PCG-U1 and PCG-U3 is their processor, the Transmeta Crusoe TM5800. While still running x86-based version of Windows and being able to run native x86 applications, this CPU is, in fact, a VLIW CPU which translates x86 instructions to VLIW instructions using the so-called Code Morphing Software and executes them on the fly. Thus, such CPU could emulate any CPU architecture unless the corresponding Code Morphing Software version exists. To speed up operation, a special cache (which is taken from RAM, 16MB for PCG-U1 and 24MB for PCG-U3) for storing instructions is used, where the CPU stores the generated routines in cache and, if these routines are being frequently used, it tries to optimize them even further. However, this cache would be cleared after each reboot, meaning that the system would be pretty slow upon each boot and every "new" action (like starting a specific program the first time after booting the system) would also be slow as the CPU will need to optimize all the code from scratch.
However, while being not very fast, Transmeta CPUs were very power-efficient. While corresponding x86 CPUs could consume up to 35W of power under full load, the TM5800's power draw under full load was only 8.5W. The Transmeta CPU consumed even less power during tasks with medium to high intensity, like DVD playback (around 1.5W). This caused the U1 and U3 to work for around 3 hours on standard small battery pack and up to 12 hours on optional large battery pack.
