For a number of years I used my Tungsten E as my main PDA. But it was getting long in the tooth and, being skint I did not have the money to buy a shiny new smart phone. What to do? Well, when I started a new job I was given a Nokia 6300 - I asked for a Blackberry, but no mission. I discovered to my delight that with a wee plugin for Mac OS iSync would beautifully add Apple Address book contacts and iCal calendar entries to my phone. A little sync calendar entry in iCal automates the connection between my Nokia 6300 and iCal every night at 10pm. Sorted!
With Spanning sync I automatically update Google calendar, so I can add personal appointment to that from anywhere.
Also my Windows PC in work with Outlook syncs with Google using their little Google calendar sync program.
Happy days. Would I buy a Palm Pre? Ohhh yes.
