Currently have a creaky 6 year old Dell which we have beefed up with memory but it needs to be retired before it falls over. This is our only computer so needs to serve us and a 4 year old. We don't really do anything beyond (lots of) internet/email/office. We definitely want one with a digital tuner. DH says it's got to be touchscreen, I wonder whether that's helpful for DC, all their school computers seem to have mice still, but I know you can use keyboard/mouse with touchscreen so maybe that's irrelevant. PC World were very unhelpful and said it was basically up to us. Is that really it? Can be a bit flexible on price, but I'm really not convinced that spending (say) £1200 is worth it when you see what you can get for less.
