Peek Mobile Email Device Rated 3 out 5 by Wireless and Mobile News
The Peek is simply for email. The Peek keyboard was called "one of the best QWERTY keyboards we've ever tried" by CNET, while some reviewers say it lacks a stylus but not style.
Peek's user interface, keys and jog wheel were all liked by reviewers and email from services like gmail, Yahoo mail and Hotmail were all easy to master and set up. The reviewers, who are used to rating cameras and MP3 players rolled into smartphones think that for a one function device, the Peek is too expensive. The no-contract $19.95 a month service plan doesn't compete with some of the wireless carriers email only plans that go on top of calling plans.
Ladies with long nails will rejoice, however, because it has been noted that Peek's keyboard is roomy enough to accommodate long nails, which the iPhone does not do.
So even though, there are few reasons for Peek-a-yays (like the keyboard) the Peek received more Peek-a-boos for the price and lack of Wi-Fi from the peak-reviewers. To see summaries of the reviews continue reading. 
Joanna Stern at Laptopmag rated the Peek 3 out of 5 for a crisp 2.5 inch display and comfortable QWERTY keyboard with dedicated nujmber/symbol row. The scroll wheel was fast but uncomfortable. Email setup for gmail was easy and simple but POP account requires a call to tech support. There is no search feature for finding email and the Peek can't open MS Word documents. Peek works on T-Mobile's GPRS network. The monthly service plan is not as cost effective as T-Mobile's $9.95 email only plan or Verizon's $15 month plan for the enV2. Her verdict is "the Peek is a good choice for someone who wants a device for e-mail and nothing but."
Nicole Lee at CNET also rated the Peek 3 out of 5. She liked the well-spaced keyboard, easy UI, the easy-to-use jog dial, slimness and absence of a long term contract but thought it was too expensive. The text and display are clear but it doesn't support HTML email. Peek doesn't delete emails in POP and IMAP accounts. It lacks Wi-Fi. The price warrants more functionality.
Tony Long at Wired, wrote "The Peek, which bears more than a passing resemblance to the classic calculator, was built to send and receive e-mail. That's it." He notes that the Peek is for Luddites who don't want to deal with anything else. He did like that is was light weight and easy to carry but could use a stylus."If dining a la carte at the tech buffet is not your idea of a square meal, then skip it".
