Darn, if they did a universal update for the app I would have been happy. As it is, I'll be looking at other IM client apps. I don't think repaying for the updated interface is worthwhile when other apps are available for less.
I really liked beejive for the iPhone when it came out and used it frequently, but there isn't any loyalty to purchasing a new app from them unless it is CLEARLY better than the other offerings.
Same went with the AirSharing app I purchased, purchased again for the Pro when it came out, and now they want another purchase for the iPad version. I'm all for developers making money but not on repurchasing essentially the same product. In that case, it seems more like a money grab.
