I agree, just started using bbsh and its great.
I am lumbered with a BB torch, now. One of thos annoying BBs with a small and recessed keyboard and I am about 2 hours away from switching back to my Bold 9000.
The vpn into the BES network is excellent for sysadmins allows access to internal URLs too so I can get to my nagios/cacti/RT interfaces as well as those for the networking kit and anything else with a webui
I can do a decent amount of troubleshooting and repairs from my BB and if I can't fix it with it I know what I have to fo by the time I get to my PC or into the office.
Even with the hours of wasted time talking to the Telco when they screw up the BES plan every 6-12 months (Optus) these have saved me countless hours and trips into the office.
