Sometimes leaving something is hard to do -- and regrets happen later down the road. Tom Perkins, co-founder of the venture capital firm Kleiner, Perkins, Caufield and Byers left the board of directors at Hewlett-Packard Corp. (NYSE: HPQ), and is now kicking himself for doing just that. Okay, let's restate that -- he really should not have left. Perkins had a penchant for weathering tough times, but the CEO mess and company results under former HP CEO Carly Fiorina and the corporate spying scandal under former chairperson Patty Dunn was apparently too much for the seasoned businessman.

Perkins left the HP board in a huff -- and he's now saying that he regrets losing his temper and abruptly resigning from the board of the world's largest computer manufacturer. Perkins, who like any mega-personality has an outsized ego to match, did hold his own in a battle of wills with those former members of HP's board (as in, former Chairwoman Patty Dunn). The way Perkins resigned from HP's board was considered by many to be uncharacteristic of the man. Perhaps he was just tired of the company regardless? Hard to tell, really -- but with Perkins' background and track record, HP would be a better place with him seated on the board rather than not. Perkin's legendary background in tech would easily make him a valued member of the current HP board. You know, since it's the largest computer manufacturer in the world and all.

Would Perkins re-join the board of HP? Probably not, since he's now on the board of Rupert Murdoch's News Corp. (NYSE: NWS) and appears to be having too much fun showing off all his toys and coddling his ego. At his age and with his background, that's what would be expected of HIM and rightfully so -- enjoying success needs to happen some time, right? HP is really on the right track under CEO and Chairman Mark Hurd and the company is in better shape than in most of the recent history of the company under Hurd's leadership, which would have matched Perkins' style and if he was still on the board. Problem is -- he won't be coming back. For Hurd -- who is completely different than his CEO predecessor -- he's be happy to have him back.
