Whilst i like my Itouch for its convenience i have yet to find many particularly brilliant apps.
The one that is really useful is Radiobox for internet radio. This means i can listen to my internet stations in the Photography studio at work without having to drain my battery on my phone.
Other than that the idea of itouch seems a bit dated. They have made it far to small to do its Primary Objective well. Thats to play music. I just cant understand why they havnt concerntrated on the Sound Quality. I would like to see a fatter version with a proper built in amp and DAC. I love the sound that my computer produces but i cant help but think the ipod should have the functionality to improve on that.
