Don't try to argue with LTD. He's know for completely ignoring facts that go against his distorted world view that anything that dares compete with the almighty Apple sucks and that Apple can do no wrong.
One-trick pony e-readers *will not* survive in the market. In its current form, the Kindle is destined for the bargain-bin. It's all about multi-purpose devices - gaming, reading, surfing, apps, everything - all on a single device that does everything well, wrapped in a user-centric, touch interface. This is the iPad. Unquestionably.
The Kindle aint it. It doesn't matter how pleasant it is to read books on it. If consumers can also do it on an iPad, they're going to choose an iPad.
You don't need to believe me. Wait a year. You'll either see an Amazon tablet/slate device released to compete with the iPad, or you'll see nothing.
