AV2 with C2ENET1 is a better rig if you are looking at expansion in the future and expandable memory for your projects.
more options - provided you can find the bits cheap on ebay.
Can load mobile project direct to mobile device with toolbox but having adequate memory is still better and easier and can cater for multiple devices and free or paid apps on your friends devices if they visit!!
C2ENET2 just gives hardware firewall and easy subnet but no real use where you have described.
Older CP2E had less RAM but now are 64Mb same as AV2.
