ok so have any of you guys used this app called LogMeIn? this app allows you to control your home pc/laptop from your iphone/ipad. the app is $30 but what it doesnt say on their website is whether or not there is a yearly membership you need to pay for or if oyu need to pay for another program which would install on your comp in order for the app to use it. does anyone know? have any of you used this for the iphone or currently on your ipad? if so how is it? what are its limitations?
