Nick -- Emailing workaholic

Nick is our resident sub-editor and therefore deals with a mountain of emails every day. Ideally, he'd like to be able to deal with some of his workload on the journey to and from work. He doesn't want to carry a laptop around, however, and would prefer a more compact solution.

He's seen some people around the office access their emails using a smart phone and while he'd love to be able to do that, his phone is too old. Nick really needs an easy way to get his emails on the go. He doesn't want anything too big, but it needs to have a large enough screen that he can view emails properly on it.

He'd also like it to feature a Qwerty keypad so that he can type out emails quickly and it needs to be able to sync with the office's exchange server. Hopefully, we can get Nick what he wants without too much hassle. Several smart phones have all the features he needs -- it's just a question of which one he likes using.
