The Apple Iphone 3GS is the most useful gadget I own. With the seeming endless amounts of applications, it has certainly helped me to streamline the contents of my handbag. With the calender app, I no longer need my filofax. I now access my Natwest accounts in seconds. I can speak to folks in the US via Skype without being in front of my computer. The calculator is easy to use, as well as the spendometer which helps me keep track of- my spending. The tubemap and Tom-Tom apps also lighten my load.
The standard camera is ok in ideal light conditions, but you may wish to download one of the paid apps to get really good quality photos in poor light. The ipod and solitaire keep me occupied when waiting for long periods. I cannot extol the virtues of the IPhone, I was not a tecchie pperson, but this has converted me. My very best birthday present. Ever.
