In a former life I used to be a programmer. Around 1986 I was shown Lotus 1-2-3.
I realized that my days as a programmer for a range of accounting applications were numbered. Then of course, Excel came along and sealed my fate.
Yesterday, I had a play with NYC way (by mycityway) for the iPhone. Then I saw the iPad version. I kid you not, this is a mind-boggling app. Well, at least in terms of what they are presenting the user. It's also fairly good at hiding how they make money. I'll leave that to you to work it out.
The mycityway apps are going to change the way we travel, when we travel with our iPads. The iPhone app is disappointing when compared with the iPad version, but it's still very impressive.
I'm interested to know what other Killer iPad apps are out there for the travel industry.
disclosure: I own and run a small hostel (www.studor13.si) and want to write such an app.
