No go for business...
Most businesses use intranet apps that are generally platform independent and only some are browser dependent. So why bother? If it has a browser, it's ok. We don't yet see the reason for upgrading to Win7. All the machines in our company are XP's and will remain that way for as long as it is technically and humanly possible. The investment priorities are very different from IT. and since IT is not CORE business but only SUPPORT.... need I detail further?
Let IT "pros" play with toys such as tablets and Win8. We're using computers to make bucks, not for the fun of it. Learning a different OS and adapting all applications and users to it is tricky and complicated. Costly too. We don't want to have to pay for all that. Nobody does.
