I have used this system exactly for one year.This has been a miracle for me as a Health care Professional. Telephone with a speaker, SMS(Text messaging), Schedules with reminders, Contacts, even internet on the tip of my finger right on the front lines!Not that wasn't enough with addition of an external card I have loaded the device with multiple medical books from skyscape.com and free calculator, and last but not least epocrates with latest on meds and lastest on journals and medical events weekly from MDCONSULT.com on the RAM which has been a heaven. I just can't believe it still its like a dream coming true...downsides with every new system is expected but only a smart man knows how to resolve problems rather than expecting to be provided with a &quot;perfect system&quot;:#1 battery at max is 1.5 days (no problem I have put chargers in the car too).#2 slow internet (I don't use that much internet only for emergency and I remember during my vacation I was able to purchase two items by this device from e-bay!)#3 e-mails at max you will get 2 lines of your e-mails (and if you put don't foward on your ISP side you will get only the headers ) why? because only in Europe they have overcome this problem not USA yet (a simple translation to english of what I was told finally by the third level tech.)However on SMS you could send a page at a time with 300-500 SMS a month for couple of dollars a month that is unbelievable.#4 device kept falling from its lose connection from my belt in going in and out from the car(no problem I purchased a great holder from Marware.com now it doesn't move)So again it is depended on what you are doing and expecting, for me this device has saved lives!
