A couple of weeks ago I switched from Verizon Wireless to T-Mobile, and at the same time had the opportunity to pick up a new cell phone. 

After a lot of deliberation I went with the T-Mobile MDA Vario.  This is the first PocketPC phone I've owned since the Samsung i700.  The Samsung was a bulky phone so I was a little hesitant at first (and as a result was leaning towards the SDA), but now that I've used the MDA for a couple of weeks I definitely made the right choice.
