I just got this through and so far I really like it. So far I have gotten almost everything up and running. The EVDO is impressively fast and I can data service on the Metro here in DC. So the coolest App has been listening to streaming radio (NPR) while underground on the Metro. Seriously cool! The other fun thing is hooking you laptop up to the Treo and using it as a modem to get internet access.
The only problem I have so far is syncing with Oracle Calendar. The current version of Oracle Calendar does not support syncing with ActiveSync 4.0 which you need for Windows Mobile 2005. It is possible to synch using a 3rd party SyncML client on the Treo… but unfortunately it is not setup on the server. Anyhow I don’t really use the calendar much so it is no that big a hang up.
So far… so good. I will post again on how it is going!
