I've got 2 sons 22 & 25. One is a software engineer (and makes way more than me) and the other is studying to be a chemical engineer. They are gamers. Board games video games etc, They both have Android phones so I was thinking of the Samsung G2 watches. $300 each is my limit. I only get to see then during Christmas time so I don't really know what they are into. I'm sure there are a lot of things I haven't thought of because I am not a gamer. What do you think about the watches? Any other suggestions would be welcome. Oh yeah they are not into quads or RC anything at all.
