Activity of The Mrs

I am looking to buy a new computer this weekend and wondered what the best out there was at the moment. I am looking to spend no more then £400 really. Only need it really for internet, Word and Excel. Any ideas?

Would this put you off buying a property? Have found a house that I like but it has this type of heating and was wondering if anyone had it. Is it more expensive? The energy cert is no worse then another that has gas central heating.

Going to Rome this weekend and wondered if anyone had any good restaurant/bar recommendations? Also what are the top things to see and do? Planning on going to the Colosseum, Vatican City and Trevi Fountain. Thank you
