I guess I have two answers to that question.
We are frequently asked by our clients if they should be considering implementing Windows 8 within their company. Our default answer, at the moment, is definitely ‘no’. The reasons for this are many, but largely revolve around the training / up skill requirements for people to work productively with the platform. Certainly, there are many benefits to Windows 8 – speed, security, new communication paths / social networking, built-in email / calendar / contact support for Microsoft Exchange (ie, no Outlook required if you don’t want it), and integrated support for Microsoft’s online services to name a few. But – at the end of the day, people need to be productive with their computers, and without some significant re-learning, they will be much less productive with Windows 8.
From a personal level – I definitely encourage upgrading, or at least purchasing the upgrade (if you aren’t planning on buying a new computer in the near future, this is a significant deal). Personally, I think it is critically important to stay currant with as many of the major new technologies as possible. And, well – its fun! I have been using a Windows Mobile phone for several months (A Nokia Lumia 920) and love it. Yes, it has fewer apps than the Galaxy S III that I abandoned shortly after buying it, but that gap is closing. And, importantly, it is rock solid and totally integrated into social media channels. The same can be said for Windows 8, so it is a very engaging operating system. I am looking forward to purchasing a Microsoft Surface Pro when it is released at the beginning of February to better test Windows 8 on a purpose-built Intel-based touch screen device. More on that later!
