You might remember the Peek handheld email device we showed you last week. It looks like a Blackberry and keeps it’s nose to the grindstone, doing only email, nothing but email and still more email for $20 a month.

It’s not going end up in the hands of most gadget lovers, but considering the demographic they are aiming for, it could do well. Laptop mag had themselves a peek at the device and are claiming that it’s simple to use. They really liked the soft keyboard and talk about how it can be tucked away anywhere thanks to it’s thinness, which ought to make grandma happy. Until she loses it.

Looking for a device that does email and only email? Well here’s a new handheld from Peek and it will only handle your e-mails.

Sure, you can scoff and say what the hell is that about, but it may just catch on. Think of the older generation, you know the ones who can handle email but can’t figure out iPhones and such. It’s only real hurdle is pricing, which will be $99.95 when it hits Target next month. Oh, and $19.95 per month to send unlimited e-mails over T-Mobile’s network. Ouch!
