I've been noticing that my 4th generation iPod Touch is very slow. I don't think there's anything wrong with the iPod. I think it's just that the processor is too slow for common apps. I restarted it and then started a bunch of apps and timed how long it took for them to open: Music 23 seconds, crashed, then started right up the second time. Spotify 23 seconds. Facebook crashed, then took 25 seconds. Twitter 17 seconds. Google Maps 18 seconds. Yahoo! Sports 15 seconds. I don't know how much faster the current version is, but it seems to me that processor speed is something Apple needs to work on.
