and run it flat out at full speed for 10 hours?

Running WCG on an IPhone/Blackberry/IPad while it is in your pocket is a sure way to prevent you from having children and possibly even shorten your life considerably. It will also create the need to add a new word to the Oxford English Dictionary:

Pocket Blister: n. a serious burn, usually 3rd degree, from an overloaded portable electronic device which is left unchecked will result in sterility for both men and women. This is usually caused by running software applications on the portable device that cause it to generate heat and eventually melt the entire device. This most commonly occurs when individuals want to run applications designed for desktop CPU and GPU chips designed for data processing on devices designed for communications tasks.

My heart monitor is net connected and is only busy 5-10 sec of every min

Yes. Why? Becasue not every device has a CPU chip that is CAPABLE of running a WCG client. It's that simple. Just because a car has a computer chip does not make a car a computer.

What makes you think that a phone runs as fast as a comptuer? IF a computer takes 4 hours to complete an HCC WU, do you reall think it is going to be a good idea to run a WU on a phone that takes 16 days?

The assumption that you may be making is that the phone is just as fast as a computer and that is the problem. If the phone IS just as fast as a computer, then it would be called a Computer not a PHONE. A phone is horribly slow compared to a computer and TOTALLY not suitable, nor is an electric water heater, digital clock, microwave oven, Timex watch, garage door opener, stop light, air conditioner, automatic door opener, PLC, digital camera, backhoe, washing machine, chain saw, telephone answering machine, billboard or anything else that has a chip but is not a COMPUTER.
