Fujitsu have been making tablet PCs for a decade longer than Apple. I had a Centrino one and it was a fantastic media machine but still a toy. It also was far superior to iPad, which is even more crippled and for fashionistas only really.
Amiga 1000 took nothing away from your C64 setup, just added the option of mouse input. A tablet PC did remove/disadvantage use of a traditional computer and real users never took it up as a new defacto replacement though. Multitouch is no help and I'm typing this using XP tablet edition's on screen keyboard.
Multitouch will never be suitable for my gaming needs either (eg Battlefield 2 on PC)
