Only thing is - the fire isn't trying to be the iPad.
Which might be a serious problem.
These also-rans seem to have a serious product-positioning problem.
If they position their device directly against the iPad, it usually becomes glaringly obvious that it is nothing like an iPad, which is often a big problem.
If they deliberately position it away from the iPad, it will become glaringly obvious that it lacks everything that makes an iPad (and thus what is expected from a tablet) great.
But this is an industry-wide problem. Most of these tablet makers are noticeably confused, and have been since the iPad hit the market.
