Sure, the Nintendo Wii Shop Channel is full of classic titles that many remember from childhood, but does that mean we should buy games on nostalgia? Maybe we've been spoiled by Xbox Live's demo system, but Microsoft's service has been around long enough for Nintendo to learn from its competitors.
Given Nintendo's tiny disk space, we don't expect demos of traditionally-released Wii titles. But these are retro titles being charged at a premium. Not everyone has played the classics, and beyond that there are original titles that have been promised. If not a full-fledged demo, why not a 5-minute time constraint, and our purchase can turn off the clock -- that shouldn't be too much of a logistical issue.
We love the little console, we really do; that's why we don't want to see WiiConnect24 (or PlayStation's no-use-for-a-name online network) function below its predecessors.
