I like Team Viewer. It's a great remote access app with better features and functionality than a lot of the PAID apps. Good support for dual monitors, too.
I think it's a little annoying to have to enter in the access codes for your own computer, especially since the 4 digit code changes every time you restart the prorgam. But I guess it's a good easy way of connecting to other people's computers to help them.
I had my mom install it on her computer, and I helped her set up her email and other simple stuff.
I also like "Key Ring" It scans all of your rewards and discount cards from places like the grocery store, CVS, blockbuster, etc. Then, instead of having to remember all your cards on your keychain, you just pull up the app! There are a few apps that do this, but this one does the best job scanning the cards.. Plus it puts the store's logo in the list of cars.
yes team viewer is very help full for lots of reasons, i used to use remote assistance until i found team viewer and there should be some option where you could sync with trusted people and it never ask for password for a connection to certain places, but maybe that is a big security risk. or for even for your own pcs would be good.
