For the month of June, if you order any product from Motionapps, you get a free copy of mDesk:

"Throughout the month of June we are offering a free registration code for mDesk with every purchase made on mDesk will be automatically added to your purchase, adding mDesk to your shopping cart or entering a promotion code is not necessary."

MDesk Pro seems to be a better solution...

I know there is a competing app out there...PDA Reach:
