the trade-in was a good deal on the SP1 but not the SP2.
it's true, Intel has overpromised such as when the announced the 5Ghz chip in 2000 which never materialized. maybe they are fibbing about the capabilities of the Core M but something tells me that, like the SP1/SP2, the SP3 will be the form-factor innovation and the SP4 will "get it right" with the chip / heat / battery life.
Here is the thing, around 2006 Intel unvieled Atom, a chip that was going be cooler and with a very long battery life. And they delivered a very hot chip with a battery life that was the same as in the Pentium M which was the one that the Atom was supposed to replace. The Atom processor achieved what was promised in 2006 around 2013.
