I am a total newbie to Arduino and have a project that I believe can be accomplished with Arduino. I am looking at the Arduino Mega2560 as it seems to offer the greatest flexibility.
The initial project requirements are:
Two servo motors x-y axis controls. Speed not an issue, precision a little more important than speed.
Servo Motor #1 < 1 amp
Servo Motor #2 2-5 amps with good holding power.
Arduino must control servos, have a graphics touch screen for Data Display and provide a keyboard for setup and user input, a wireless link (Blue tooth or WiFi) to a Windows laptop. In the future, I would like to add a separate Arduino to function as a remote control and remote data display perhaps using Zigbee.

Brevity is the spice of life my friend, unfortunately, your response did not advance the discussion and did not impart any useful information. I was very specific about what the hardware requirements were. As you will not be building it, and I certainly do not need you to build or program it for me! What I wanted were some straight forward responses to a question and get ideas from other forum participants as to their experiences. Perhaps someone might say that the Mega2560 is overkill. After all, this forum is for guidance, not sarcasm. If you have nothing to add to the conversation, kindly butt out.
Flexibility means more I/O as applied to hardware which was the basis for the original post.
This is for a one off QAD project. Hence the decision to investigate the Arduino systems. After the project, it will be trashed and we don't want to invest time and money on more complex and costly architectures including PCB design etc.
Perhaps I should put it in layman's terms: Will the Mega2560 permit the use of those modules, as outlined in the original post, without conflict? If there are conflicts, can they be managed by (flexibility) wiring to other ports? What are some of the gotchas? Any EE, worth their salt, knows that gotchas will kill a project. Too many of these smaller system boards boast many I/O pins and when one gets down to counting the available bits, there are scarcely any left to run a toaster without sacrificing other desired functions!

The info you need about the arduino, not just how many I/O but programming capabilities are freely available if you go looking,
The fact the you do not want us to program it for you means you have someone to do that, they should be looking up the feasibility of different controller platforms as they will know exactly what you want.
Asking advice here requires some form of give and take info wise.
If you simply asked, what car do you buy to go from Melbourne to Sydney.
I would say, Toyota Prius.
Someone else, Bugatti Veyron.
SOomeone else Hummer.
All because of different perceptions, please lighten up, I googled QAM and it looks like its a programmed development and design philosophy. Is this a project?
