Remember when we announced the Peek Pronto and how funny it was that anyone would even consider a messaging-only device? Who would possibly want that in the company of BlackBerrys and iPhones? Well, Amazon has struck up a deal that some may find to be pretty hard to pass up: lifetime service with no monthly payments. If you have it in you to fork over $300 for the Peek Pronto, you can enjoy a lifetime of email (Exchange mail included) and all the text messages you can handle. Assuming your Peek doesn’t get lost, stolen or broken, you really are set for life — though we’re not exactly sure what happens if Peek, umm, ends up going away.
