So a quad-core tablet isn't for you, this doesn't mean nobody has a use for it.
This isn't Apple where you have a one size fits all product.
There are plenty of existing dual core Android tablets out there; and single core ones; and ones with small screens; and ones with big screens; etc.
Most iSheep under-use their $600 iPads and they have no choice because there is only one model (with various amounts of storage)
The good thing about Android tablets is the variety. Most people could save $400 and get a Kindle Fire, but if they want a big boy tablet, its nice that things like the Transformer Prime exist.
I would love to have one of these quad-cores with the new Ubuntu for Android running on it.
