Michael Dell, the founder and chief executive of Dell, has ramped up into full salesman mode. According to Mr. Dell, people who go out and buy a top-of-the-line PC with Windows 7 next week and then purchase Office 2010 when it arrives next year will enjoy a computing catharsis, The New York Times reports. "You will love your PC again," Mr. Dell said, speaking on Tuesday night at event held by Silicon Valley’s Churchill Club. "We have not been able to say that for a long time." Dell knows all too well how customers’ relationships to their PCs changed for the worse during the Vista years. About 80 percent of Dell’s business customers skipped Vista and remained stuck on the old Windows XP. "Newsflash: It’s an 8-year-old operating system," Mr. Dell quipped. Over the last eight years, Dell has gone to rather drastic lengths to route around Vista. The company has been the most aggressive Tier 1 supporter of Linux, placing it on a range of computers. Dell has also poured vast sums of money into revamping its computer designs, offering everything from pink rigs to laptops with finishes done by contemporary artists and bamboo sheaths that wrap around desktops.
