Hardware suggestion

Hello!

I'd like to buy some Arduino hardware, but am not sure what is the most flexible setup.
I don't have a specific project but my projects would be either android orientated and smarthome and internet applications.
That means sensors, RF trancievers, Android apps, webclient, webserver...
I was thinking of buying:

  • Arduino Mega ADK (do I get everything I'd get with "Arduino Mega2560 Rev3"?)
  • Arduino Ethernet Shield Rev3 WITHOUT PoE Module

BTW, what is the difference between "Arduino Ethernet Shield Rev3 WITHOUT PoE Module" and "Shield - Ethernet"? Which Ethernet Shield would you suggest for Mega2560/Mega ADK?

tia and regards,
Mara
