1/2 is definitely beatable, but it is going to be swingier than .50/1 because the players as a whole are a little better. Beatable, but a little less fishy than at lower levels.

That said, there are some adjustments that you have to make, most of which previous posters have already mentioned (blind stealing, blind defense, knowing when to semibluff and value bet). I think one of the most important things you must learn is patience. You don't get action on all of your big hands at 1/2 like you do at 0.5/1. Unlike lower levels, 1/2 players sometimes fold when they have nothing or a weak draw and you don't always get paid off on your big hands. You can't let impatience cause you to make mistakes that cost you money (i.e. tilt).
