For those wondering, the computer in the picture is a Microsoft Surface table computer (http://www.microsoft.com/surface/en/us/default.aspx
). Its almost 5 years old now but isn't marketed to the general market due to the price I think.
As for the whole dropping the name Mac from OSX, it might be do to Apple slowly trying to move away from OSX and only want to focus on iOS, aka slowly kill OSX. 70% of Apples money is made from iOS (http://arstechnica.com/apple/news/2011/10/despite-record-mac-sales-70-of-apples-revenue-comes-from-ios.ars
) and basicly put, iOS is in a better position for Apple then OSX is for the futre. OSX still can't beat Windows due to the lack of programs (there and many, MANY more programs/games on Windows then OSX) so for many people Windows is the better choice. On iOS though, they have a large selection of programs and games which helps them for a better future in computers. Not to mention, OSX doesn't always keep generating more money after the initial sale, iOS does (30% per app, and whatever on going fee's). Apple loves this, regardless of what they say to the public since they made I think like 3-5 billion last year on iOS app sales, nothing to sneeze at and more then OSX made after initial sales. And with how locked down and App specific it is, it would be harder for people to leave iOS (instead of platform neutral things and sites).
Examples being people only know now to look up their mail from their eMail app and not the website or get their news from their Newpaper App instead of the companies website it suddenly makes change a LOT more harder to another OS that isn't close enough.
I can also see Apple trying to sell its locked down nature to companies as being better for them/less power for the customer. iOS is just the newest console on the market. Can only do what the hardware maker says it can do. And when the consumer has less power, the companies have more power and have no problems abusing it. We see it already with todays bigger consoles. Games and such only are what are 'approved' and money talks in that game. Also prices don't really go down since you can't shop around. And while it's cheap to make iOS games now, without OSX you can't make iOS games so its back to spending a fortune on a Developer Kit for a locked down hardware that costs way too much money.
