Just because the Apple iPhone does something in a certain way, it doesn't mean that it's the perfect way of doing it and that everyone else should copy it.
Hang on, actually it does. Treobble is the latest in a growing number of programs designed to replicate the iPhone's intertia contact scrolling feature, this time for Treo devices, allowing you to peruse your address book simply by touching and sliding your finger up and down the screen.
It would be unfair to say that's all that it does though, because there are plenty of other features that help you enhance your contacts book.
For instance, you can view all data from a particular contact, initiate a call, send an SMS message or an email, all without having to use the pointer.
The scrolling feature works surprisingly well unless you have lots of contacts, in which case it can get quite jerky. It also lacks the ability to perform incremental searches of your address book, which can get a bit annoying.
Nevertheless, Treobble is probably the closest thing you'll get to the iPhone's cool contact-scrolling function without actually upgrading to the Apple device.
