Peek Pronto is the follow-up to last year's best new single-purpose gadget. Just $80 without a contract (with a $20 monthly data plan) the new edition has push email on up to 5 accounts, unlimited text messaging, MS Exchange compatibility, a PDF and DOC file viewer, and more font options. The latest version of the operating system, Peek claims, is 50 percent faster than the original. These upgrades directly address each and every flaw in the original Peek. Peek Pronto is exclusively at Amazon until March 31., at GetPeek from April 1., and at Radioshack from April 8.
