Excuse me? Take those batteries that millions handle daily out of their hard shell (and heavy) handleable cases, remove the hardware and ports necessary to access them safely in the devices, and perhaps you would see a few more fires and injuries reported than are already reported with those safety precautions in place. High density energy storage devices like LiPo and lithium ion batteries have been known to spontaneously discharge and cause fires and injuries to users even sitting untouched inside sealed cellular phones and laptops. The batteries Apple uses in its iPad are without protective hard shells, and are not designed to be consumer removable or replaceable. You can call it Apple apologetics if you want, I call it engineering decisions.
As to 32 or 64 bit or not. Apple is preparing for the future. Adobe has not released Flash in a 64 bit version. It is the only proprietary standard graphic format in widespread use on the Internet and every user of Flash is totally dependent on Adobe upgrading its proprietary code. It has not and shows no sign of doing so. Apple is backing HTML5 and H264 open standards that can do the same things as Flash with out being dependent on proprietary code and is already completely 64bit compliant.
So Apple could not do what every other manufacturer who uses LiPo batteries can do. Good to know they're not as good, and cannot make a simple, removable package like all other manufacturers!
Adobe has not released Flash in a 64 bit version.
Because they support lots of platforms. The 32 bit version of Flash just works in 64 bit OSes, including Snow Leopard. Now, how does an Apple 64 bit OS support that archaic 32 bit technology called Flash?
