After spending tens of dollars on iPad apps, I can tell you one thing - developers are still in the dark re the UI of this device. However it doesn't stop them from charging more than $10 for an ever crashing app.
While iWork apps prove to be stable and usable, others are just riding the hype. I couldn't finish a 2 minutes session of Elements, without a crash. It didn't stop the developers from charging $14 for it. And yes, I am talking about a periodic table, with fancy pictures. Compare it to an amazingly useful GoodReader, that costs $0.99, and you start to see how misguided the iPad apps pricing is. SocialReader is another great idea done wrong, that cost $1.99.
And while Things is overpriced but useful ($19.99), the guys from Omni Group are asking for $49.99 for OmniGraffle, a diagram application.

I have to admit that some of the best applications are the free ones. NYT is awesome. The same for Bloomberg and BBC. Gaurdian's Eyewitness app is great too.

Now, I am all for pricing applications based on their value. But many of the apps on my iPad are simply unstable to the point of unusable.

I have a short list of apps that I really like to use. But I will wait until sanity regained in the pricing of iPad apps.
