Chuckle! Ummmmm ..Apple did NOT invent magnetic detachable covers,just like Apple did NOT invent the smart phone, touch screens etc, contrary to what the crazy Applebots like you keep claiming. Not to mention the very thin (3 mm) magnetic detachable cover on the suface doubles as a keyboard. Microsoft invented a fast, pressure-sensitive digitizer that enables Tap Detection; an algorithm helps determine whether you meant to press a key or not . The iPad’s cover is just a dumb piece of plastic. What's great about that? The gap between the Surface's’s smart cover/keyboard and the iPad’s dumb piece of plastic oover is like the distance between the earth and the moon.
Again, you blatantly lie, constantly, to buttress your false statements! I never said they invented them, I said they pioneered their use on tablet computers. However, if you were to research them, you would find that Apple holds many patents in magnetic detachable connectors, and Microsoft holds none. That's right, Microsoft simply is copying the work of others, while Apple is the pioneer.
For instance, patent US6030229 filed by Apple in 1998 and issued in 2000 for "an electromagnetic detachable connector".
US7311526 filed in 2005 and issued 2007 for "magnetic connector for electronic device".
US7351066 filed in 2005 and issued in 2008 for "electromagnetic connector for electronic device".
US7641477 filed in 2008 and issued 2010 for "electromagnetic connector for electronic device".
US7645143 filed in 2009 and issued 2010 for "magnetic connector for electronic device".
US7762817 filed in 2008 and issued in 2010 for "system for coupling interfacing parts".
US7901216 filed in 2009 and issued 2011 for "magnetic connector for electronic device"
US7997906 filed in 2010 and issued 2011 for "techniques for coupling interfaces parts using moveable magnetic elements".
US8087939 filed in 2011 and issued 2012 for "magnetic connector for electronic device".
US8177560 filed in 2011 and issued 2012 for "magnetic connector for electronic device".
This is a mere fraction of the patents issued to Apple for their pioneering work in magnetic catches, there are many more that predate these in he 1990s. Microsoft's name is no where to be found in this area. So Apple indeed, did pioneer the magnetic detachable cover for tablet computers. You are a microsoft bigot who touts a company that copied a concept pioneered by others, and the product is not even available. Talk about pure stupidity, you got it.
