Ivo Jansch of Ibuildings has taken a look at a different sort of spin on Apple's iPad device and asked what potential it has to affect the PHP companies out there.

I see the iPad (and the non-Apple alternatives that already exist or are on the way) as a game changer. It brings new ways of consuming content and will reach audiences that the laptop has never reached. [...] In any case, the iPad is a game changer. What does this mean for the web and for tech companies such as us? First, it's nice to see that Apple is pushing open standards heavily with the iPad. [...] Second, the typical architecture behind most iPad apps (and other mobile applications for that matter) is to have a thin client on the device, and a rich API as the backend.

Ivo talks about the one of the key pieces of technology behind it all - the API that your service provides for iPad/iPod applications too hook into. Without a well-built, solid API to interface with, your application can be world class but not be very useful at all.
