The StarWarsShop currently has a number of items featuring R2-D2 that would be pretty cool to have around the house.
This R2 projection alarm clock is pretty neat, but I'm not sure that R2's beeping would be enough to wake someone. Maybe if he also came with that little electric tazer thing that he used on Salacious Crumb, that might help wake someone up.
How cute is this R2 shampoo bottle/soap dispenser? OK, so it might be a little undignified, but hey, R2 was already a drink cart - how much more undignified could he get?
