However, it doesn't support SSE2. This is a hardware capability. Only Office 2013 and Windows 8 have a hard requirement on that specific piece of technology.
So, therefore (and in my opinion), we should continue using it until it cannot sufficiently handle tasks that only Windows 8 and Office 2013 can handle (as an example of course). Because THAT, again in my opinion, justifies a hardware upgrade.
As for BO$$, necro-lover and frantaylor: Please, take your fingers out of your ears and stop doing 'lalalala' while at it mkay? Please respect each others opinion, how boldly stated it may appear to you.
