Wow what a bunch of hateful people!
I have been using both Apple, MS, Linux on a combo of different hardware platforms over the years and all have a purpose.
I have a 2011 MacBook Pro 15 maxed out with 480GB SSD, 16 GB ram Thunderbolt monitor running OS X 10.8.3 office 2011 for mac
2010 MacBook Pro 13 240gb SSD 6GB ram running OS X 10.8.3 office 2011 for mac
iPhone 5 64gb
iPhone 4s 32gb
2010 MacMini Server
Dell Servers running VMware 5 with multiple server os's
Dell XPS 8500 maxed out running Windows 8 pro 64bit, office 2013 pro
Alienware m11x3 maxed out running Windows 8 pro 64bit, office 2013 pro
Alienware m14x2 maxed out running Windows 8 pro 64bit, office 2013 pro
Acer W700-6691 Tablet PC i5-3317u CPU 4gb memory running Windows 8 pro 64bit, office 2013 pro, came with BT keyboard, Docking station $699. with Black Friday discount from Newegg.com pretty much the exact same hardware as the new MS Surface Pro and Windows 8 has sold more OS's in a month than OS X in 4 months.
The Acer feels as fast and can do way more than my iPad's can ever think of include manage Enterprise servers and workstations.
All have good and bad points but cant say that any one of them is the end all.
the Fan Boys on both side are really sad and need to wake up.
My MacBook Pro's can barely play current games anymore...
the Acer can almost out perform the MacBook Pro's in WoW, GuildWars and many other games for 1/3 of the total price.
