I do think iOS should have multi tasking on the iPad. I don't know how well it works on the Samsung, but I do hope Apple thinks of a good way of doing it.
The inability to have a Skype video conversation (whilst seeing the video) while browsing the web is quite a big limitation to me. It can be very useful to see two things simultaneously in countless situations, especially if the iPad aims to replace computers for many people.
Ahhh..... therein lies the rub, doesn't it?? The implementation.
Samsung's tablets don't have horrible, not real multitasking at all, "choose from a VERY limited choice of apps to *ahem* multitask *ahem*" because their software engineers can't code.... quite to the contrary- their workforce is probably 80-90% as talented as Apple's! They are employing top-notch minds. The reason why their "multitasking" (sorry, I simply cannot use that term without quotes & keep a straight face, as what Samsung offers is clearly NOT true multitasking) is so incredibly shoddy is because true multitasking on a mobile OS is currently IMPOSSIBLE. I believe that what Samsung has done (& make no mistake... it sucks) is currently the absolute BEST that can be done. And THAT, in a nutshell friends, is why Apple is waiting.
Let's parse this out a moment & think about it. Many, many, many apps rely on the use of the gyroscope & accelerometer to respond to tilting the screen, shaking the device, etc as input, correct? So.. logic tells up that right off the bat, precisely ZERO of these apps can work well in a true multitasking environment. What are the chances that you'd want the same reaction in the two different apps at the exact same time? Ok... what about games? You KNOW that somebody would immediately want to Skype while playing the latest iteration of Infinity Blade or the like. So, obviously, to keep that from being a lagtastic horrible experience, any app that uses a high amount of resources would have to be nixed. Basically, any implementation that I can currently envision includes HUGE trade-offs. I think all they could do is a minimally handy implementation like Samsung's where you can only choose super lightweight apps like calendar, mail, YouTube, or web browser to sit side by side. Even that has HUGE caveats. For example, people claiming that they copied Samsung (which is indeed what it would be doing, were they to adopt this approach), also.. The control piece.. for how much Apple gets a bad rap for "controlling" the user experience & Android gets praised for the opposite.. it's odd that nobody finds Samsung's forcing of you to use their crappy tiny selection of pre-selected apps for "multitasking" draconian. I, for one, would NOT like to see this on iOS. What if Safari was one of the apps & I wanted to use Chrome? What if stock calculator was the only choice & I wanted to use HandyCalc? I, simply put, could not... I would be (like a Samsung Galaxy Tab owner) forced into dismally small selection of apps for my "multitask" experience. Sounds miserable. I seriously cannot fathom who is pushing for this.
