Earlier quoted context omitted.
"We don't need the low end. Let them have it." Didn't the american car companies take that route too? And steel mills. and... mainframes I think.
It doesn't make it a stupid decision. Levano can already take the low end (or Asus will). IBM sells their low-end while it's still worth something, rather than fighting a losing battle.
Then Lenovo puts a few more coins into R&D and takes the midrange. Which IBM gladly gives up because the margins aren't high enough...
This has happened more than a few times across several industries - American cars, Japanese electronics, mainframe/mini/microcomputers, etc.
EDIT: Also see apricot computer. Which did the /exact/ same thing - outsourced the production of it's "commodity" computers, losing its special sauce, and lucrative service contracts. It was gone in a flash. Sir John Harvey-Jones even did an episode of the UK show "the troubleshooter" on them. It's a sure way to make a quick buck this quarter, but horrible long term.
