Just like what I predicted in my earlier articles, ultrabooks have dropped down below $600. My reasoning is very simple: if Apple can sell a similar thing for $1000 to $1300, there is no chance for other brands to sell for more than the half.
The Vizio was initially priced at $900, now $598 after only few weeks. The Folio is a great ultrabook and a great deal at $498. Both use the Intel secondary generation Sandy Bridge CPU. When you buy a portable computer, make sure an Intel i3, i5 or i7 2XXX CPU inside ("2" means 2nd generation). Older CPUs are not good enough and newer ones do not offer significant more benefits.
