Palm, Inc., which has struggled in recent months after making a splash with its Pre smartphone, will be bought by HP, the world's largest computer maker. The deal has been approved by both companies' boards, and should be wrapped up this summer. HP will get Palm for about $5.70/share (about 20% above today's closing price), or about $1.2 billion. That's a pretty good deal, considering that in the months following the launch of the Pre on Sprint's network, Palm's share price topped $16. But marketing blunders hindered the Pre's more widespread adoption on other carriers, and the company's very existence has recently seemed in doubt.
