Is it possible to travel with only an iphone? I have to say, it isn't too difficult. For the past week, I've been depending on only an iPhone as my primary computer, and the whole experience hasn't been bad. I'm composing this from the Philadelphia airport before my departing flight. Someone asked about a Bluetooth keyboard after reading my last article and I have to admit I don't use one. I've just been typing on the keyboard, butt keep in mind, I'm 5'2" and weigh in at 95 pounds—fully dressed. A keyboard was completely unnecessary for someone my size; but if you happen to be any larger (which would include all males and most females over the age of 16), you may want to invest in a Bluetooth keyboard.
