Konfabulator - a Study in $hareware

The folks at konfabulator probably made their fair share of money with their recent sale to Yahoo. Lets look at what they did right, and what they did wrong:

Right:

Good Looking
Simple
Standard Technologies
Cross Platform
Sold for lots of moolah

Wrong:

Charged for the runtime
No IDE
Memory and CPU heavy
Cried foul instead of fighting, and may have been wrong
GUI over substance
