Recently I took a look at how "finger friendly" build 23XXX compared to 21XXX,here is my thought:
1. In 23XXX,the Start Menu and close/ok button are in the bottom,this makes sense,I do find it quicker to operate,while in 21XXX,you have to extend your finger to the right top corner of the screen to click close/ok button.
2. in 23XXX,anything require finger to click become bigger, for example,the owner info,in 21XXX,the input area is very tiny,while in 23XXX,it's very big.
3. the bad thing about 23XXX is that,some softwares were designed based on 21XXX,therefore cannot keep up with 23XXX's new skin,for exmaple Pocketmusic Player v5.3.5,at the end of installation,it askes you to select language, there is no any button (ok or close) for you to proceed, the installation is stuck. Although I do find a way to get around this issue by press back button of the TP2.
But there is no get-around solution for Resco Photo Viewer Pro v6.33,the tools (zoom,open folder etc) are blocked by 23XXX's bottom menu,this makes Photo Viewer Pro v6.33 useless.
I think Resco Photo Viewer Pro v6.33 is much better than newer version v7.0 when it comes to full control of picture viewing exprience.
If you are fan of Resco Photo Viewer Pro v6.33,then 23XXX is definitely not your choice.
People like me are stuck in the cross road of 23XXX and 21XXX, we like 23XXX's more-finger-friendly,but have to leave it because there is no alternative picture viewer that is up to the standard of Resco Photo Viewer Pro v6.33 and compatible with 23XXX.
