No matter how much people mock Bill Gates and Microsoft. Everyone will agree the fact that its because of him that every home has a computer today. It was during the time of huge expensive VAXs and PDPs, Bill Gates had a dream of making computers affordable and usable by everyone not only scientists and Engineers.
In today’s world :
Windows PC is now a necessity.
MAC a luxury.
Linux is an option.
I know there are a lot of people telling MAC is better, Linux is Open its just a way to make themselves feel better for not using Windows. There was so much skepticism about Windows Vista, it has actually sold 20 Million copies more that what XP sold in 2 months. Its a fad these days to use non-windows operation system, just a fad. Everyone will slowly roll back. Yeah there will always be a small group of loyal MAC and Linux users but Windows will remain ubiquitous.
I’m a MAC developer have been using Macs for last 3 years. Having experienced both the worlds I still feel from user point of view and development point of view Windows is the best.
