Sharp Hiptop 3 / Sidekick 3

Ok, I want to buy sidekick 3 but I'm not sure. In Poland there are no sidekicks , so I will need to buy it from , I guess, USA or UK. Before I will do it I need to be sure that I will be happy with using sidekick 3. I was searching for opinions of others and the comments were good as weel as bad. The bad ones discouraged me to buy it but I really want it ! I'm not gonna give up so easly. I need a pro opinion of users of Sidekick 3. But honest opinion! Tell me everything about sidekick (bad and good things). Please.
