Craig Pringle is a MVP in Tablet PCs, that said, his opinion about the Fujitsu U1010 is in one word, valuable.
Over all the U1010 is a very usable device. There is a lot packed into this tiny package and every aspect of the design shows that it has been carefully thought out. The price is very reasonable and performance is surprisingly snappy. All told a solid offering.
In my opinion the U1010 could be a very good UMPC for many. The main reason is the design which has been proven to work in Tablet PCs. I would prefer to see on it a little more powerful processor and an extra USB port but... Nobody is perfect.
