Quite right there young Andy.
The point I was making about having everything in one device is that you risk losing everything should that device be lost/stolen/unrepairable. Now, as a retired DJ, I always kept the audio mixer, amplifiers and cd players as seperate units, so if one should fail, I can get a replacement in place very quickly. If however, the DJ has all of this in one unit, and the equipment decides to go belly up during a gig, everything is lost. I apply the same logic to these all-in-one communication devices.
Now moving back to the I-phones, the IT person in me says, well, as long as everything is sync'ed or backed up to external sources, the case for IPhones is quite good.
My Sony Ericsson W610i, being nearly 3 years old is capable of storing and playing music, can handle email via the IMAP protocol quite well, and has calendar functions, etc. It has a strange function where it can make phone calls as well, whats that all about
It confuses me why people want to upgrade, upgrade their phones all the time, but whatever floats yer boat.
