Here are some interesting tidbits out of Sony Ericsson. They are apparently working on an Android-based Tablet. Perhaps they will have a "PlayStation Tablet" to go with their "PlayStation Phone"... Also, they are deep in development on an LTE device that will probably hit in Asian markets first. Interestingly, they also had this to say about Microsoft's Windows Phone 7, That's a pretty good endorsement, and a mild 'slap-in-the-face' to Microsoft. What do you wanna bet he has an Android?

sony already announced the S1 last week. it will be the true plystation tablet. it will be a sony vaio based product ( no ericsson affiliation). - (Exclusive: Sony 'S1' PlayStation tablet (updated) -- Engadget)
I thought they said it wont be till around Q4, but anything could happen between then, especially with the quad-core Tegras shipping by then.
