A report from Consumer Intelligence Research Partners seems to support that theory as it has emerged that out of all smartphone users, iPhone users on average pay the most expensive cell
Cell phone carriers really want your business, so much so that they offer deals that seem almost too good to be true, especially when it comes to the coveted iPhone. It’s not unheard of for a customer to grab one of the devices for less than $200.
The iPad is en route and this may be the first cool thing you'll buy for it. Instapaper developer Marco Arment is hard at work on Instapaper Pro for the iPad. For those who don't know, Instapaper [App Store, $4.99] is a simple bookmarking application that takes any piece of content on the web and allows you to save it for later reading. The original iPhone app, according to the developer's preview, has been reworked into an iPad version to support the iPad's doubled screen resolution (the iPhone version, per Arment, looking "awful" prior to the conversion).
The end result is Instapaper 2.2, a "universal" version of the app which works on both the iPhone and the iPad (as well as looks good), which Arment has managed to work out via a feature in the newest version of it iPhone OS SDK.
