Alarm watch - computing device?

I have joined this project with my old Thinkpad tablet. The tablet, running just Android 3.2, was no longer useful as a software development device (how it originally served) and was standing next to my bed to play music waking me in the morning. This is also not so simple, two days a week it must play an hour earlier.

I realized that the tablet can perfectly do its alarm clock duties while computing something useful for Einstein@home. It is always connected to the power adapter, and still has wireless alive. It has no problem in doing tasks within the time line.

Developing the concept, would be an interesting idea to have the alarm watch for sale that also does computing for Einstein@home. It could be decorated properly, and bring points to the owner. Maybe would it would be possible to develop and offer for sale such a clock in the community shop? Would be a more interesting thing to buy than T-shirts and mugs.
