For the price it should comes with the keyboard dock and a bunch of other quality accessories
As long as nobody here is making the irrational "all tablets should be under $300 argument"...keep in mind that the T1 came out STOCK MSRP at $400, which caused near-insanity last spring. If you have an hour to kill, go read the Amazon reviews on the Transformer
in reverse chronological order (old to new) and you will see how low people can sink in terms of desperation for a digital device. Boycotts of price-gouging sellers. Chinese-conspiracy theories. All kinds of nuttiness.
Asus did a good job, and they knocked the Xoom (and maybe the Thrive and the Iconia and the Galaxy 10.1) out of the equation. Toshiba and Acer even fiddled with the prices ($50 store gift cards) but to no avail. Too little, too late.
It makes no sense whatsoever -- if $400 was last-year's T1 price -- for the T2 to lead at the same price-point. Put the two side-by-side specwise and the T2 blows the T1 out of the water. I totally agree with you that $500 (let's remember, for the 32GB model) feels like a notebook pricepoint, and you're not getting notebook features. Aside from raw CPU, you're actually getting a lot more (IPS display, 2 cameras, GPS, acceleromter, touch screen, and so on).
If you're right, by mid-summer the price on the T2 will break somewhat, and we'll see it drift down around $400 for the 32GB and $450-$500 for the 64GB. But just look back 1 year or 2, and you'll see that's a lot of tablet for the money.
