> Sorry: it is the apparent complexity that drives the sale.
Maybe that holds true for some applications, but for the most part (in my experience at least) 'hiding' is not synonymous with 'having the right stuff at the right time'.
To make your application appear complex is just going to increase the barrier to entry.
I'm fairly sure the only reason I'm in business and have been for a long time is because the first contact with our application is as simple as you could possibly make it.
That it can do a lot of other stuff is assumed until needed. People sometimes send support mail about very advanced features indicating that the 'power users' are definitely able to find their way. But for 99% of the audience the first level is all they'll ever get to and they're happy there.
If you sell a luxury car, apparently it has to have buttons.
But when you look at those buttons on a 10 year old car you'll see which ones are the ones that got used (because they wore!). As a rules, it's the same buttons that you'll find on a Lada.
But cars are 'conspicuous consumption' for some, so they are not to be compared with a web-app.
Something like 'mint' has enormous functionality but they've made it relatively (as easy as you can make it I guess) easy to get on board because of this exposure trick.
Good software uses context. Over-complex design does not drive sales unless you're trying to send all your competitors down a dead end street.
Microsoft word, that pinnacle of design, is only where it is today because of lock-in, if not for that (users emailing each other word documents) and some pretty ruthless marketing it wouldn't stand a chance.
Text editing is - as someone quoted here - a solved problem, but it seems that there still isn't an easy way to get what you want. Possibly there will never be (because text editing is inherently complex), but that should not discourage those that seek to enhance the user experience with minimalist approaches.
To me the apple audio line of products is a great example of how minimal + gradual exposure is the way to enormous sales, don't forget they weren't the first company to produce an audio player (or a smartphone either).
