In reply to jamesgreenfield: yeah that's fine for getting up hills, or you could look at a triple if your really concerned.
The bianchi has a good pedigree, although you can get better spec bikes for the same money or a little more. If your worried about the cassette size £35-£45 will get you an upgrade from a 12-25t to something like a 11-28t.
Have a look at the bike spec below as a comparison to e Bianchi. I think these are all ten speed as well, which may make upgrades easier.
The giants have a good spec and you can either go aluminium or carbon for a little more money! The felt will be similar to the bianchi but with 105 group set.
If your going to pursue it I'd get one of these, if not spare some money and get the Raleigh airlite or someone will be along to tell you about decathlon bikes.
As long as you like it and it fits is the main criteria, plus you may want to support your local bike shop.
There are some good priced Eddy Mercx bikes on chain reaction cycles and have a compact or triple option too.
Not trying to put you off th bianchi, but think you could get more for your money.
