Probably not very hard, but if they had done it, they would have all the hype now wouldn't they? RIM has been in the business for years, so why didn't they start an App Store this well marketed a long time ago?
This is a simple case of a start-up (Apple) changing the way business is done and capturing a share of the market from older companies who were to entrenched in the old way of doing things. RIM can still catch up, and like you mentioned, maybe even surpass Apple by getting rid of obnoxious parts, they just need to get their act together.
