So many people depend on their Blackberry units, including clients of
mine - since they aren't served by an enterprise IT staff, they're
stuck if the patent infringement lawsuit shuts them down.
 Any ideas as to another neat integrated solution for contacts,
calendar and emails delivered wirelessly to an organizer?

Due to RIM having a high possabilty of going to court over their
network, A good idea would be to look at the PDA/Phones that use
Microsoft and Palm operating systems. Sprint/Nextel and other cell
phone carriers like T-Mobile have PDAs that are similar to the RIM
blackberry, but use PocketPC.

The Palm Treo 650 combined with GoodLink server is a fantastic
alternative to Blackberry.

GoodLink functions very much like the Blackberry Enterprise Server. It
wirelessly syncs your PDA with your Outlook email and organizer
information. There is no need to run a desktop redirection software
like MyMail.
