Sadly, that's not my experience.
Recently I purchased an AK Jr out of curiosity. While the AK Jr sounds better, I hated, hated, hated the lagginess of its touch UI. Tapping one page back from the now playing page can at first seem to not register, but is actually lagging. After 3 seconds, you think the first tap didn't register, so you tap again. By the time the UI catches up, you've gone two taps back to the home screen.
Another issue is that the AK Jr is very picky on ID3 tags. Cover artworks in PNG? Sony, no problem. iOS, no problem. The AK won't display them. APE tags? The AK gets stuck when doing a library scan.
The whole experience with the AK Jr is infuriating. I've already put up the AK Jr for sale, and I can't wait to get rid of that damn thing.
