Let me count the many, many ways....
- Spreading FUD (fear, uncertainty, and doubt) utilizing a variety of techniques regarding competitors rather than improving their own product.
- A 32,000+/- limit on the number of rows of data you can have in an Excel spreadsheet. YOU try and sort a 200,000 line data file when you need to break it into 32k line chunks first. Makes a bad evening so much better.
- A well-deserved reputation for software ("bloatware") that pushes users into unnecessarily purchasing new hardware because of poor resource utilization. In other words, much M$ software in my experience is a pig for resources, such that a relatively young machine grinds to a halt under the burden of carrying the latest OS and software like an oxygen-starved asthmatic.
Now...the list could go on, and the above is only my opinion...but I have a 250k line sort going...yeargh.
