You don't need a fully fledged (and slow and clumsy and heavy and bulky) computer or laptop to send and receive email. Dedicated email devices and appliances are a cheap and easy to use and oft mobile alternative.
1. BlackBerry - Email Device
Almost as small as a cell phone but still equipped with a familiar QWERTY keyboard, the BlackBerry devices emulate mobile phones in versatility, too. Not only can you use email but a BlackBerry is also an organizer, gaming device, web browser and, maybe, GPS-powered navigator.
2. iPhone - Email Device

iPhone Mail does a great job rendering emails and attachments pretty, swift and useful. A few more shortcuts (such as marking multiple messages read, search, text snippets or a unified inbox) would be great, though.
3. Peek E-Mail Device - Email Device
Your email address and password is all you need to set up the handy Peek email device with most accounts — and off you go exchanging emil on the road in a focused and sleek manner.
