For most of the attorneys, the Blackberries are pretty good devices for keeping caught up with emails. There are a few attorneys, however, who really require a robust platform for emails as well as Personal Information Management (PIM) and phone use.
The Blackberry is usable as a phone, but I think that a lot of the attorneys feel that the 7730 is a little big to hold as a phone and the lack of Bluetooth limits their headphone choices.
The Blackberry's biggest weakness, however, especially in OS 4.0 seems to be in the PIM arena and specifically contacts. Actually, OS 4 presents a few problems even for users who have no contacts. The fact is that OS 4 takes up a lot more headroom than OS 3.7 did. Blackberries run slower on OS 4 and often freeze up with the hourglass while it's processing something or other. This is kind of annoying when you are typing a password and you get the hourglass and have no idea what characters of your password were grabbed properly.
It is, however, a major annoyance when you have a good sized address book (lets say over 1000 contacts). When you have that many contacts, the Blackberry often locks up for VERY LONG periods of time while it does whatever operations it does to sort through the contacts, especially if you have content protection turned on.
Whereas a Palm, or Palm Treo chugs through contacts very quickly thanks to it's much faster processor.
Ahh, the things I wish I knew before we got all set up with Blackberries...Would have been nice to know that the Treo processor is 10 (TEN!) times faster than the Blackberry's.
Anyhow, if anyone from Research in Motion (RIM) is listening...it would be REALLY REALLY helpful, if you either came out with a much faster Blackberry very soon, or changed the OS so that it would always reserve some processing power for the user interface.
It SERIOUSLY degrades the user experience when you have to wait and wait for the @#&$ing thing to finish doing whatever it is that it's doing.
