Of course this was bound to happen! Best way to make money from a free os: open an online app store!
The Chrome store is going to run on Chrome only which may be a struggle at first. Then again, who’s going to buy Chrome apps if you’re not using Chrome? I do believe Google may be spreading itself pretty thin with all the balls they have in the air, but I think it’s a good idea to have an app store ready to go in case Chrome takes off.
