Gadling has done a follow-up review on the Peek email-only handset, and the review gives the Peek a mostly positive impression.
The Ideo designed handset apparently performed it single task admirably, sending and receiving emails using the T-Mobile network with just a short delay, and incorporates an OS that is easy to use.
Of course it may be a tad expensive at $99.00 and $20.00 per month simply to just be able to send and receive emails, but if you’re just have a simple on the go emailing facility then maybe the Peek email-only handset is the way to go.
