I love the iPhone, with all its cheapie little apps that you can download for 99c or $1.99 or at most $2.99. Got a good deal - they were selling them for €49 here, and the package isn't too dear.

Some of the apps I use: Truphone, for calling Japan or America for the price of a local call; Eirtext Pro for free international texts; Files, for carrying around Word files; New York Art, for seeing what art shows the New York galleries have on; Special Day for knowing whose birthday is coming up. Lots and lots of music apps too - what about Shazam: you press 'tag this' and hold it up to hear a tune, and it can (usually) identify the song and singer and record label.
