Jax works as a hub between your iPod and the web. The application, which loads up in iTunes, lets you download lyrics, album covers, videos and transfer all that to your iPod.
Jax can import and export videos from all the main online video sites such as YouTube, MySpace video or Yahoo Videos. Album covers can also be downloaded from all the different Amazon sites in the world.
We quite liked the Music Map, which links up artists according to whether they worked together, share the same influences and many more other parameters.
The music visualizer is also fun to use, although it seems more like eye candy than anything else. Some users will also like the "On the Go" section, which gives you all sorts of information like stocks, weather or gas prices.
These can also be synced to your iPod.
In a way, and this has been mentioned before, Jax is way too similar to Life2Go. It actually feels like a revamped version of Life2Go with added web features.
iPhone users should also seriously consider before buying Jax, as the iPhone can do pretty much anything that Jax offers. In terms of performance, we also noticed that Jax did tend to crash iTunes every now and then.
Useful when the iPhone wasn't around, Jax feels more obsolete than anything now. Users with older iPods may find some use in this multimedia iTunes hub though.
