I for one can concur that I have a bit of tablet fatigue.
I have owned iPad 1 & 2, Xoom, and Galaxy Tab and have sold all but the iPad 2.
While the iPad 2 is by far the best of the bunch, I find myself using it less and less and looking at the cost to use ratio and it is becoming quite undesirable.
Honestly, the only reason I keep the iPad 2 is for my 4 year old daughter and because I don't think it will go down in value between now and Christmas.
I am thinking Dell was ahead of their time and a 5" phone would be ideal for me. Either that, or someone needs to make an AirPlay enabled tablet display so an iPhone 5 can be used in a tablet form factor. Much lower cost for the same thing as an iPad... Or maybe a dock somewhere on the display for the iPhone (I think there is an Android tablet that does this?). These tablets are worth about $200-$300 to have any longevity, in my opinion, not $499+.
I think you're making it all up.
