you are feeling what I did when I had my 4th gen Touch for a couple weeks. I really grew to like it and the more I "tested" the better I liked it. However I never did adapt to the limitations access wise and knew I never would beyond just accepting the inevitable and dumbing myself down enough to do it "The Apple Way".
Also a limitation you may never encounter is for Audible content. You are limited to ONLY two accounts on the device at any given time. We have 4 or is it 5 accounts so no way to really get the most out of Audible for us and Audible is very reluctant to consolidate accounts though I understand if you ask nicely enough the might do a one time consolidation for people. Because we use audiobooks from Audible a lot, that was a big short coming for us.
But I really like the way the apps worked. Some were quirky but not bad. Then again I was spoiled with the Retina Display...wowzers!!
