This time I finally went for a PDA/phone.
Just recently bought an Imate JAMin with Windoze Mobile 5. I looked at the Blackberry's but it was the kiddy like nature/layout that put me off. I can touch type, so I don't need a keyboard built into the face of the device; once I got the hang of the stylus thingy; I was pumping out books each time I messaged a bod'. The JAMin could be set up better than a BB IMO and do so much similar function wise compared to the laptop I use all the time.
You see people with company funded phones and wonder how they got away with convincing Bob in accounts they actually needed the latest and greatest BB or similar but I'm more tending towards believing that people should be able to specify what phone they want for work use, just so long as they pay for it. The employer can supply the SIM card, and if their was a 'very easy' way to swap SIM's on the fly, what's stopping workers moving between their own SIM card and the employer ?...
The suits higher up may have to think about having secure area's for data storage that no phone within 50 metres will receive a signal via bluetooth/IR to nullify the bad habits of sloppy workers later on, sort of like a 'shutdown zone'. Like the poster above, I loaded on Opera mobile and I've been blown away by the mobility geekiness it instills; makes one feel very empowered by it all.
