Call me pessimistic.

Every viable web startup idea that I can think of has already been done by other startups who have been there many years before. Many of these startups' products look very polished and usable, that I can't begin to think of how to make a substantially better product that would encourage people to jump ship onto my product.

For example, one of my ideas is a repository hosting service. But why the hell would anyone use my service when there's already GitHub/Assembla/BitBucket?

I'm thinking of just copying other startups but charge less as a possible strategy. Is this a good idea?

When I see demos of web apps (videos, screenshots), I can't help but notice that they are all almost exclusively done using Macs.

Is there some secret to why everyone's doing this? Why am I not seeing more demos on Windows? Or Linux for that matter?
