So here's another speculation on the Apple XCODE lockup clause: that the iPad CPU is not the ARM variant that most analysts think, it's actually a PA Semi dual core Power Architecture CPU running ARM emulation. The argument is that the die size is too big for the ARM Cortex, and it's too small for existing PA Semi designs unless they reduced the L1 cache. The system software will switch from ARM emulation to native code with iPhone OS 4.0, XCODE will produce fat binaries targeting both architectures, and iTunes will deliver the correct native binary when you install an app. Everybody who follows Apple's instructions will get an immediate 40% turbo boost when 4.0 boots.
