Windows Store: More Flexible than Apple, and a 80/20 Revenue Split Over $25K
The Big One: Devs Get 80% of Revenue over $25,000
Developers can offer their software for free, but otherwise the minimum price is $1.49 (95p), which is higher than the 99 cents minimum found on most other stores.
The firm also distinguishes itself by offering software writers 80% of the revenue from app sales and in-app purchases using its payment process, if their app earns more than $25,000.

The only question is whether or not that 50 cent increase will discourage more sales. If not, it's a huge win for Windows/WinPhone app developers. And even though most developers won't make more than $25K with their apps, it's nice to know that if you do you'll be getting $20K of that $25K. That's $2,500 more in your pocket.
Also Big: Approval Process Transparency
This feature is also pretty big given the well-known problems that developers have had going through Apple's approval process. The Windows store will basically have a process by which you'll get to check on the progress of your app's approval. The guidelines will be clear from the get go.
Flexible Free Trials and Distribution
Another cool feature of the Windows Store will be option for developers to do feature-based or time-based free trials. Developers also have the choice of managing their customer transactions directly - "for example, with newspaper subscriptions, or to adopt a business model with offline fulfillment, such as for auctions. We don’t mandate a specific transaction engine and developers can use their own." - MSDN blog
The store will launch in the early months of next year and developers will then have a pipeline to the largest computing platform of all, since Windows still makes up around 90% of the PC market.
