I've been waiting quite awhile for you to release an iPad version of Mobilinc. I've been satisfied with the iPhone version and felt the price of $20 dollars was reasonable but I won't be paying an addition $50 dollars on top of that for an iPad version.
Very disappointed you didn't upgrade the existing app to a Universal app. I would even consider paying a small fee like $10 dollars to upgrade the existing software, but I don't think you can ever convince me that the HD version is good enough to warrant a $50 dollar price tag.
