i have 3 boys 8,4,2 and have been able to keep there pc in top notch condition for like ? i am guessing around 3yrs now. not once have i had to do anything to my pc except getting new mouses and keyboards. and the best thing is my 8 year old is teaching my other two son's there 123's, abc's, and reading. they are entertain before dinner and on saterday's. they can walk up to it anytime they like, in that stated time and play and learn. i am thinking of getting them another pc and doing the same to it. they are very combetitive when it comes to a few things like this. keeping in the spirit of not a nanny but an educating tool. it really helps, in more way's then one. thank you.
