This was one of the main reasons I did not buy an iPhone 4, passed on the iPhone 4s, reluctantly gave up my Blackberry for an iPhone 5. If Blackberry would have come out with a half way competitive smartphone, I would still be using them. I smiled when I read the above linked article.
If you are reading this and want to sell a iPhone 5 keyboard, send me a one. If it doesn't kill the battery on my iPhone and it works and does fall apart if carried. I'll by it. If it junk, I'll just keep my mouth shut.
