Pebbles -
Bl(cr)ackberry devices are still 'mainly' used in the corporate environment. They basically allow corporate email to be sent in real time to a mobile handset and in turn the handset allows real time sending of replies back - all via the systems in place at the office and deals with airtime providers.
Recently, to add more market appeal, more and more consumers or non corporate people have started wanting them, and so newer handsets have arrived that build in a phone, PDA functions and leisure functions too.
I toyed with the idea of getting one, then junked it as I don't really 'need' it.
Britwife - Enjoyed yer 'raspberries' lately?!!
Hope this helps a bit!
