buying T420 online

I wanted T430 for next year however due to my old tz notebook that turns off by itself, shoot bluescreen or bear hot floor, I had to do some fallback.
$1499, not cheap but not expensive for the spec.
What I am missing are
SSD 300G,
USB 3.0,
Longer Battery.

Maybe I am gonna have that function for my next notebook.
Now I am quite satisfied with the spec of T420 with price.
I have to c in fact if it really works after I get it.

Anyway, I bought it today and it's coming.
