I've got a Fujitsu Siemens Amilo M3438G arriving on Tuesday. Various specifications available, but for around £900 you could get :-
Pentium M 1.83Ghz
1024mb DDR2-533Mhz
256Mb nvidia Geforce 6800 Go
100Gb SATA 5400rpm hard drive
17" Widescreen WXGA/WUXGA screen (1280x900 or 1920x1200 i think, depending on the model)
All the usual wireless, remote control, media player etc
We ordered ours through an NHS employee home computing initiative thing, so the prices may be different at retail to what we are paying for the lease.
