This is not a very practical mini computer. The design has been lopped off from a larger Mac rather than designed from scratch. The full-sized keyboard means it's still quite large - certainly not pocket-sized. A more practical approach would be to have a smaller, pocket computer as a companion to a larger laptop (or desktop computer) rather than try and make the smaller laptop the main computer. Almost 20 years ago (in 1997), a British tech company called Psion released a small handheld computer called the Psion Series 5.

Suprisingly, no one has made something similar (that I know of). I imagine it could be made today with an e-ink screen for extra long battery life. A pocket computer like this would be perfectly capable for everyday tasks like email, wordprocessing and using spreadhseets (but not for video or graphics work).
