Day one and great so far. I was using Tiny Twitter for my Windows Mobile client. It worked well but had some odd little features such as displaying the avatar fullscreen covering the content. It was also a bit heavy on memory. I wasn't really looking for another client but noticed the application name on a recent tweet and decided to check it out.

First glance, it felt nice and fast. Memory usage was lower than Tiny Twitter and it has some nice features such as displaying twitpics inline and themes. I've used it all day and it appears to be stable and very useful once you get the basic UI down.

Highly recommend trying it if you're in the market for a twitter client on Windows Mobile. Get Twikini here
