I've been using Windows 8 since the Developer Preview which I found to be be barely functional. Consumer Preview was much much better, and now I have Release Preview working really well as a Virtual Machine on Virtualbox.
However, I also have it running on a Dell Inspiron Duo so am able to benefit from the full touchscreen experience. I must say that this really brings Windows 8 to life. I really like the gestures and they have become instinctive really quickly.
IE 10 has not made me love IE anymore than the last few generations of Microsofts browser. So I did not hesitate to install Chrome as my main browser and it works as well as I have come to expect, but is not currently a metro app of course. I suspect this will come though.
Today I have downloaded and installed Office 2013 preview and it looks pretty nice so far. I'm already a fan of Skydrive, and being an early adopter - I've been lucky enough to be able to hang on to the 25gb of cloud storage that Microsoft were initially offering with this, which is nice.
All in all I'm very impressed and very hopeful for the success of Windows 8, Windows RT, and Office 2013. The Surface Tablet also interests me greatly and I suspect I will end up getting one. Windows Phone 8 is another important piece in the jigsaw but I think Microsoft will struggle the most here in terms of making an impact on the dominance of iOS and Android.
Exciting times though. Can't wait to see how it all unfolds.
