Hi, I have two children, in 5th and 7th grades. They both seem to need access to a computer for school and I've let them use a laptop, but I've found they tend to wander off and spend hours playing games. Various attempts at rules of use, parental controls, etc. have pretty much failed. I'm thinking that maybe a desktop in a central location, might be a better choice. I will be better able to see what they're doing. I have an iPad they can use when they want to play games. I haven't had a desktop in years. I'm hoping for some feedback on whether this is a good idea or if there are considerations I've not thought of. I'm also hoping for some recommendations on what models or specs to look for. Thanks for any help on this.
