So I've been using a T-Mobile Sidekick 3 for a while... I use it a lot for comunication on the go, and for work purposes. I started using Sidekicks with the Sk2, a very durable and well-designed unit that served me faithfully for about three years before it was time for a new model.
I'm feeling like it's time for a switch, but i'm in love with the Sidekick's general design philosophy prioritizing simplicity and ease of use overall. It feels good in my hands, the keyboard is great, and all the functions are easily accessible and extremely straightforward. I'm not quite ready to let go of the product line yet, but Im hesitant to try another SK since the quality seemed to take a nosedive with the 3.
