We currently have 1 desktop and 1 laptop. Considering just cutting cable altogether and tethering a laptop permanently to the TV Via HDMI strictly for downloaded kids cartoons. Only need internet and phone. Quite frankly, the only use for TV we have is treehouse for our daughters and the occasional hockey game for me and we only have it because it came with the current cheap plan we are on. We can and always have downloaded everything else. So we will need a new laptop. How powerful a laptop will we need to hook up to a 42" TV. Guessing we won't use it for streaming or anything since we have a desktop and already good laptop for that.
