I just love my iPod Touch. I received it as a gift from an elderly aunt who specified in her will that with some of the money she left me, I HAD to buy an iPod (she knew how much I loved gadgets but would be too cheap to buy one).
I have had it for over a year and the rare times that I do forget it when going out of the house it is like forgetting my wallet. I took it Europe and it was a great compact way to bring music and pictures as well as access wifi hotspots.
Apps are awesome. I had one to check changes to flights with my airline, AIR CANADA.
I like LIVE CAMS, CONVERT UNITS, iTRANSLATE, FREE WiFi, FILES LITE, Currency, Dictionary, Flixster, Google Earth, Calculator, Stocks, and Twitterrrific.
