Just found a journal that writes about personal and ubiquitous computing and looks pretty interesting. It is published in London by Springer. You have to pay for every article but can browse through the subjects, read good summaries and write to the authors. So it's worth a look even if it is scientific.

Because you have to login go to this page first: SpingerLink - login as guest (right side) and then go here: Personal and Ubiquitous Computing
