Coming in these days: Hybrid HD from Seagate. Goal: Updgrade old Tablet PC HP TC 4400 from 7200 SATA HD to hybrid HD and SSD to compare performance and recommend (or not) to upgrade a five year old Tablet PC (which actually is running Windows 7 SP1 x64 and Windows 8 Developer Preview with 4 GB RAM just fine)
On site: Fujitsu Q550 Tablet with Windows 8 Developer Preview. Lack of decent CPU leads little use. External display with low resolution.
Sent back: Acer Iconia Tab W500. Tried it with Windows 7 and Windows 8 (Dev Preview), good concept, needs better hardware (case must become smaller and lighter, needs Windows 8 to be released, docked scenario not standing stable on table).
