I disagree with the article. Outlook 2003 is more stable, has more usable features and caches with Exchange. Windows XP Pro is easy to use and stable. Software is often times blamed for hardware and driver failures. I am a Microsoft Business Solutions pro
and Microsoft is top notch with their support and software. They fix bugs and security holes after testing making sure they work.
Competition is good to keep innovation going and Microsoft is innovating.
Did I mention SBS 2003 Rocks! Shadow Copy is awesome, Exchange 2003, Remote Web Workplace. This is the easiest server I have ever worked with and is number#1 for small business!
