pros:-having a PC & phone in 1 digital device.cons:-breaks easy-can not remove the battery(internal) to 'cold boot' the phonewhich basiclly means if the software ever hangs, good luck.-service is less then average due to a not so good internal antenna.-so many repair calls to T-Mobile, they have created a new dparetment - the,'Sidekick Customer Service' to handle the workload and still the phone wait is on average 1 hour, give or take 10 minutes.-T mobile store locations(brick & mortar) can not help when the phone breaks. They give you a chair to sit on while waiting on the phone to talk to the new Sidekick Customer Service department.btw: I am on my 3rd refurbished in less then 4 months :-(BIG headache
