I'll admit it... I'm a Claws-lover. The finger-friendliness of Modest is nice, but Claws is much more of a classic email client paradigm (i.e., it's just like what you'd use on your desktop) and much more powerful (imho) when multiple email accounts are concerned. Likewise, you can use Claws on your IT or on your other computers, regardless of the operating system and have a completely seamless move between all of them.

(Also, just so that everyone knows... Claws is themable, meaning anyone is free to come up with a more finger-friendly design if they'd like to.)

The only thing that Claws is missing is an easy conduit between it and the default maemo Contacts app.
