Apple
Acer
.44% increase for Mac compared to 3% increase for Tiny little Acer... who gained more? and who is getting more buzz?
You need to think relative. That's about a 25% increase for Apple and a 73% increase for Acer. Good for Acer. However, Acer gets lost in a crowd of Windows PC manufacturers that have seen nowhere near that kind of growth. Like your guy says:
Between 2005 and 2006, HP increased its marketshare 2.5%, or five times what Apple did
HP's marketshare actually grew by 14%. Apple grew by 25%.
And that's worldwide. Apple's US marketshare surged in 2006 by 32% to get it 6.1% of the market. Apple is concentrating on the US market, where it matters most.
