I won't be upgrading until 802.11ac is finalised and I recommend this to all people.
Well that is pretty well how most engineers like me have worked regarding everything for a long time.
This applies to anything in the consumer field from cars to computers
You wait while everyone else, the "early adopters" in marketing jargon buy the latest 'thingy'.
They can then get all the problems and the bits that don't work, that fail early etc.
Once it has been stabilised, the updates/bug fixes brought out........
The price will have come down
Only then is it safe for you to buy.
Of course if a sizeable section of the consuming public was not obsessed by the latest thingy, always wanting something new, and indeed willing to pay over the odds for it then this sort of thing would not happen, and products would be properly designed in the first place.
