The iPad is a nice device, but it has flaws and short coming. Apple has chosen to have these flaws and short comings in their iPad.
Anyone who doesn't admit to these flaws and short comings are too biased, because every product has flaws and short comings.
Sometimes those flaws and shortcomings are so irrelevant to the end user experience that they don't need to be constantly rehearsed. For example, I suppose my hammer has 'flaws and shortcomings' but it's worked without complaint or issue for years. I guess if I say 'hey it's a good hammer' I am being biased since I didn't also say 'it could be lighter and last longer though, my hammer isn't really that great, feh!'.
If there are other hammers on the market that 'do more' or 'have more features' it's entirely irrelevant to me, if the device does what I want it to.
Playing the spec game is a waste of time, comparing checkbox lists of features is pointless - see anthonymoody's post earlier.
Nobody needs to confess that the iPad lacks things if those things don't matter to them, even if every other device in the world has them.
