Comment Two things... (Score 1) 427
The first is if it becomes a TRUE replacement for the things that I put into my pockets... ALL of them: loyalty cards, credit cards, keys, etc.
The second is if it replaces about, oh, 80% of what I use my cellphone for: scanning the titles of emails (and quick deletes thereof), texts, GPS/locationing, and, oh, telling the time. =)
Give me those two things with a decent interface, and I'm in.
