You don't need Aero,its only eye candy at best,if you want Aero go to your local sweet shop,personally its very easy to get Win8 looking great especially with my Firefox themes and I don't miss Aero at all,besides only Vista and Win7 ever had Aero , its not a must need feature that does a lot which we know does very little.
Also we all know Microsoft drop features and change things now and then,so no point clinging on to something that has gone.
I've seen a lot of changes since DOS 6.22 days and if I can live with the ever changing Microsoft operating systems then anybody can,if not go to Linux.
I would rather see DOS come back then Aero,at least I would find DOS 10000000000x more useful then Aero but as we all know not point living in the past.
