I have noticed two new(ish) blogs dedicated to subjects close to the heart of paperless archaeology:
Archaeograph is run by Noel Hidalgo Tan from the Australian National University. I have linked to an earlier article of his use of tablets to record details of rock art in Thailand.
Arch-iPad is run by David Beard, a British freelance archaeologist working primarily in Germany. He is more focused on the iPad as a choice for field data collection.
I have added these to the blogroll.
