I am not going to believe in any of this until it actually happens. Windows 8/8.1 still sucks too.
Remember the same garbage was spewed out last year saying that Q4 had an improvement of something like in shipment increases. Q4 ended up with same as Q3. Shipment increases didn't materialize into unit sales because there were very few appealing systems in the mainstream price range and they were disappointed with Windows 8. That translated into huge inventories that's impacting the industry even now.
