The world of tech mergers and acquisitions continues to get interesting, as Hewlett-Packard and Dell Computers escalated their bidding war for the Fremont data storage firm 3Par. When last we checked, HP had seen Dell’s bid and raised it to $1.6 billion. Dell called that offer, hoping that the giddy geeks at 3Par would want to go with its family for the same price. But yesterday, the Merc reports, HP took it up more than a few notches to $2 billion. Just so we’re clear: 3Par’s stock was trading at $12 a share before this whole shebang started. HP”s offer now values the company at $30 a share. Don’t get too greedy, 3Par guys. Careful how you play this. But damn.
