The last issue of IEEE Pervasive Computing is devoted to smart phones.

The mobile or smart phone is ushering in the real age of ubiquitous computing, and we shouldn’t undervalue its importance. This issue highlights work that presents specific smart phone applications as well as programming infrastructure for further development and studies of emergent uses.

Papers deal with various aspects ranging from social serendipity (the one by Rusell Beale) to the use of camera phones. The interesting point here is that the topic is addressed through various angles (not just the technical point of view). However, it's curious to see that location-based services does not appear that much in this issue. More later, I need to some time to read those papers ;)
