IBM and Canonical are working together to provide better desktops at lower costs:
“If a company is a ‘Windows shop,’ at some point it will need to evaluate the significant costs of migrating its base to Microsoft’s next desktop,” said Bob Picciano, general manager, IBM Lotus. “American businesses have asked for a compelling alternative that can help them free up PC expenses to use for more strategic collaboration and business transformation projects.”
Maybe this explains the reluctance to go with “7″. It just costs too much for what it delivers. The compelling alternative are cloudy collaboration packages on Ubuntu GNU/Linux thin clients, often on recycled machines or new. That seems a lot like what I have been providing schools for the last 7 years. Eventually business catches up to new/old ideas. Organizations that intend to make money more efficiently using IT should examine the price/performance. If they don’t their competitors will.
I recommend Debian GNU/Linux. It offers performance and flexibility at a very low price.
