Seesmic describes their WP7 application as beeing able to do the following:

Customize your mobile dashboard the way you want! With Seesmic for Windows Phone, you can simply manage your Twitter and Facebook accounts from an intuitive, beautiful app

I have been trialling Seesmic for Windows Phone for the last couple of weeks and found it to be a great experience. The benefit that I see with Seesmic is that it supports multiple accounts. For me with a personal account and an official account for Swedish Tech Report it is great beeing able to just switch between Twitter accounts. You can also post to multiple accounts at once.  If you want to quickly switch between accounts you can simply slide your finger to either the left or the right. However that is not the only thing that it is supporting, it also support others such as Facebook and Salesforce. Cool thing with Seesmic is that it eliminates the need for other software installed onto your Windows Phone unit.

Cool thing is that if you swipe your finger to the right you will see what is currently Trending on Twitter.  Another cool thing with Seesmic is that you can use the builtin Windows Phone search to search Twitter and find for example interesting Tweets.  Though for me the favorite thing is that I can access my favorite lists on Twitter right there in front of me.  You can really access everything right there from the dashboard right on your device.

What is cool is that Seesmic shows nearby Tweets. I have found it to be a fun feature to check if I am in the middle of Gothenburg to see if I  am seeing somone nearby me that is currently Tweeting, cool way of using the geographical function in my smartphone. If you are a fan of Retweet you have the with or without comment type of Retweet available.  So far I have tried both on Seesmic so far and found them each to work without any trouble for me.

Conclusion: It is a great Twitter client that I am really enjoying using.  If you are looking for a Twitter client that supports multiple accounts you can not go wrong with Seesmic for Windows Phone 7.  At the moment it is my default Twitter client. Check back tomorrow when I post hte next part of my Twitter clients for Windows Phone 7, examining Twitters own client for Windows Phone.
