PCs...

"Atleast on a PC you can CHOOSE. Try choosing on a mac (natively)..."

All new macs are just an x86 pc-s, you could run windows and linux on them. Apple is using the same hardware as any gray box would, but they put the intel reference bios replacement firmware (efi) into their system. All they did was to get rid of the pc backwards compatibility stuff windows requires. Then they added it again, this time as software so windows could run natively on their systems.

We really never saw any inventions coming from microsoft. The suface system was showed by a japanese scientist a few years ago and the multitouch interface was developed by a us university. Microsoft either bought them or simply stolen them.
