Hi I got my iPod last year and it came with OS 2. something on it. I do not use the iPod much at all. Just for a few podcasts occasionally and just fiddling around with it. Now some times I come across an app I want to install but it asks for OS 3.0. What I am concerned about is that I read somewhere that OS 3.0 is slightly slower than OS 2.0. Is this true? Do you think I should upgrade?
