I ordered a set of emates so that we could use them in non networked classes. They worked well as proto netbooks but the problem was they were not networked so you had to save on a floppy and print with a very early infra beam. It really was about 10 years to early.
It was also pretty indestructible if dropped unlike an iPad. It even spawned a rival from Tandy using Windows mobile which was in colour and wireless. I was going to pilot the system but they went bust!
However the eMate saved Apple. Jobs was very taken by the design and it formed the blueprint for the Apples that followed.
