As Bill Gates steps down from full-time work at Microsoft, well-wishing cheers and not-so-nice jeers are echoing from Silicon Valley.
After 32 years of competition and acquisition, Gates managed to ruffle some feathers, while still making some famous friends. After the end of this month, Gates plans to spend only 20 percent of his time as a Microsoft chairman. The rest of his time will be devoted to the Bill & Melinda Gates Foundation and other pet projects.
Now technology company chief executives, founders and presidents are bidding farewell to Gates and the legacy he created at Microsoft. They may do it with a crack at his dancing skills or a quip about him stealing their dates, but many will still give him credit for three decades spent changing business in the technology world.
Others have high hopes that he will continue to change the world through his foundation, while some are just breathing a sigh of relief that his bullying days are over. Here's what they had to say about Gates's career and future.
Scott McNealy
"I wish him good luck. I think he is a very smart guy. It will be nice not to have him beating up on me, but I'm glad he is doing something good. I think he has a big job ahead of him. I prefer to see him spend the foundation's money than leave it to the next guy. I've got to believe that founding entrepreneurs must roll in their graves when they see how people spend their money unsupervised after they're gone."
When asked if he will miss Bill Gates, McNealy said: "I don't get paid to have feelings. But I wonder if he'll miss me."
Scott McNealy is chairman of Sun.
Steve Jobs
"Bill's retiring from Microsoft is a big deal," Jobs told The New York Times in January. "It's a significant event, and I think he should be honoured for the contributions he's made."
Steve Jobs is chief executive of Apple.
Michael Dell
"Bill's vision and commitment to open innovation have been pivotal in driving standards-based computing and a new wave of productivity. I think you'd be hard-pressed to find someone else who's had a greater impact on driving computing into every element of people's lives."
"I've always had great respect for Bill's passion for the potential of technology and really think he personifies entrepreneurship, not only as a proven technology visionary but also a business strategist. Bill's shown a great deal of courage over the years, pushing the envelope in everything from IT innovation to public-policy discussions."
"Bill is one of a handful of IT industry leaders whose work has literally changed the world by making technology more ubiquitous and accessible for people everywhere. Many of today's game-changing technologies are possible in part because of the framework built by Bill and his teams at Microsoft."
"That said, I think Bill's most lasting contribution may well be the Gates Foundation. Bill and Melinda are an inspiration, investing their energies and bringing billions of dollars to some of the world's most pressing problems.
"I don't think we'll see him letting up. If anything, the drive that's characterised Bill during his years at Microsoft will likely intensify, as he turns his full focus to the foundation. We should all stay tuned for what's next."
Michael Dell is founder and chief executive of Dell.
Mark Cuban
"Bill is unquestionably a legend who has had a far greater impact than most people understand. While the business stories about Bill are many, my favourite Bill Gates story is one he didn't even know I was party to."
"Back in the 1980s, Comdex was not just an industry confab, it was the ultimate party. I was dancing at one of the many events with a couple of girls who were clearly out of my league. All of a sudden, one of their friends comes over to us and tells me they are leaving to go to party with some guy named Bill Gates because he was worth, like, $60m."
Mark Cuban is owner of HDNet and the Dallas Mavericks [a basketball team], and former chief executive of Broadcast.com.
Mitchell Kertzman
"I guess my view would be that I can imagine a time in the mid-to-distant future when nobody remembers Microsoft or Bill's role in Microsoft, but everyone will know of the Gates Foundation and its contributions to the world."
"If Bill can bring to the Gates Foundation the same drive, determination and relentlessness that he brought to Microsoft, then he'll be one of history's great and lasting heroes. This is a new arena, when we will all be rooting for Bill to vanquish his 'competitors': disease, ignorance and poverty."
Mitchell Kertzman is a venture capitalist at Hummer Winblad Venture Partners, and former chief executive of Sybase, Powersoft and Liberate Technologies.
Philippe Kahn
"The industry is transitioning from the PC to the world of the iPhone [and] Google, yet Bill's legacy will endure."
Philippe Kahn is chief executive of Fullpower Technologies, and founder of Borland Software.
Bill Veghte
"There's a bunch of things that I have learned. Having the scale of ambition is at the core of it. [Bill would say:] 'When you think about it, don't think about it in millions; think about it in hundreds of millions.'"
"The second thing, I would say, (that) has been so important and inspiring [is]: there are people [who], as they go through life, get money or get power or whatever — whether it be in politics or sports. The true test of the person is: when you get that power and you get that money, does it corrupt the soul?"
"We were in a meeting the other day on our approach to search. It was just Bill, myself and one other person working through some things. Toe for toe, [Gates] is a guy [who] is at least as passionate as us. He's seen everything. He doesn't have to sit in this meeting. He's as passionate, as aggressive and as excited as anyone else."
"The thing that is so inspirational for me about Bill is that, with all that he's done, his hunger, his aspiration, his optimism hasn't dissipated. How he's chosen to apply that power, that money, that capability is inspiring."
Bill Veghte is senior vice president of Microsoft's Online Services & Windows Business Group.
George Colony
"'Constructive monopolism' is Bill Gates's single most important legacy," George Colony wrote in his blog.
"He has not been an innovator in technology — in polite circles, we would call him derivative; in less genteel terms, we would call him a plagiarist. Gates has been a business innovator, not a technology innovator."
"As I look back, I think that Gates's 'constructive monopolism' most closely parallels Thomas Edison's. They both created pretty good technologies and then worked, using many means, to get them accepted by more users than their competitors. [Nikola] Tesla and [Steve] Jobs are two sides of the same coin."
George Colony is chief executive of Forrester Research.
Robert Metcalfe
"Bill Gates is a great guy: really smart and he's not evil, even though I've criticised him harshly. I wrote the first column criticising Microsoft for anti-competitive behaviour. It appeared in Computerworld, [marking] the beginning of my journalistic career on 25 February, 1991."
"In my column, 'Viewpoint', the headline was: 'Is Microsoft abusing its power?' I had problems relating to Bill Gates after that because...
