Suggest you read some of the reactions to Windows 8 in this and other Forums and then make up your mind if W8 is for you. Some like it but the overwhelming response, as far as I can judge--and I have tried the pre release versions, is it is a most unwelcome introduction by Microsoft for a number of reasons. These include the rather silly step to remove the simplest of everyday PC requirements, the 'Start' button and the failure to include Windows Media Centre as standard but there are others. Probably the greatest irritation is forgetting that touch screens for desktop users are hardly a cheap or ergonomically desirable alternative.
The laptop/desktop as we know it in Windows 7 and other OS's will remain a preferred option for most of us for many years to come . Maybe merging the ways we use tablets phones and desktops has some merit but this is not the way to tackle that. I personally am keeping fingers crossed that Windows 9 will bring some sanity back into the Microsoft OS world and its release will not be long delayed.
