Thanks for your advice - I guess I really want to know if the 10/100 NIC is sufficient for what I want to use it for or if I need to go to 10/100/1000. Both are incorporated into the laptop from what I can tell by the specs. The advertizing sort of uses scare tactics to say things will stop streaming at 100Mbps soon as everyone is going to 1000Mbps. I doubt that but how would I know.
I have to decide between i3, i5, i7 as well and I really can't find a good explanation as to the advantage of one over the other in consideration of price point.
