Mar.2，Inside iPad: iPhone OS vs Mac OS X
作者:范范 日期:2010-03-03
Apple's new iPad is facing criticism for using the streamlined iPhone OS rather than the full Mac OS X, but Apple has a number of reasons for aligning the iPad with the iPhone rather than its desktop Mac platform.
While Apple's new iPad was widely anticipated to run the iPhone OS well before the company officially announced it, some observers have decided that it would make more sense for the tablet device to use the full version of Mac OS X instead, in order to enable the device to run a wide array of existing desktop applications.
Such a strategy would have resulted in the iPad looking more like Microsoft's Tablet PC and OMPC devices, which run Windows XP/Vista/7 with some extra software that enables stylus and or touch features.
Resolution problems in mobile devices
A primary problem with running a desktop operating system on a mobile device is that it would devote a lot of the available screen real estate to elements designed to support a mouse-based interface. While the iPad offers the same 1024x768 display resolution as the first iMac models, it squeezes those pixels into a 132dpi, 9.7" screen rather than the original iMac's 15" (13.8" viewable) display.
