English to Chinese Tech/Engineering Computers: Software

Next time someone tries to sell you some software that appears to be a bit too close to sleight of hand, check very carefully the customer references of people actually using the software in this way. According to a leading industry analyst, only two EII vendors can give any decent customer references at all. The software industry has years of practice of writing convincingly argued whitepapers that spin a compelling case, yet only when customers hand over hard cash do they seriously invest in the development to make it work. Always remember the caution used in the wonderful film The Princess Bride: "Life is pain, and anyone who tells you different is trying to sell you something."

下回要是有人拼命向你兜售被说得天花乱坠的某个软件，一定要认真听听实际使用者对此软件的意见。据业内一位知名分析师声称，客户只对两家EII厂商的产品还算满意。软件行业编写论点充足、摆出诱人理由的白皮书这一做法已有多年，但只有顾客乖乖交钱，它们才会认真投资于开发、确保产品可以正常使用。别忘了佳片《公主新娘》中的那句忠告：“生活是痛苦的，夸你与众不同的家伙总想骗你什么（？？？）”
