I don’t actually need one more cluttersome crAPPlet. The Google Voice web interface works fine for calling to/from abroad and it’s reasonably cheap to use: $0.02 to $0.10/min, depending where and when.

Sorry, but I’ll take a good Bell 2500 phone (with mechanical ringer) over any cell, with or without headgear any day. They got the design right as far as ergonomics and sound quality circa 1960 and very few modern phones are more comfy to use.
