It was one of the first times in computer game history where gamers could simply connect to their ISP, start a game and choose to play via the Internet from the multiplayer optionscreen.
And the Wi-Fi-only version lacks GPS. Also, videophiles may dislike the fact that the iPad's screen lacks wide-screen dimensions, so you either get black bars above or below wide-screen videos, or, if you choose an option to fill the screen, some of the picture may get cut off.
To wit: The tachometer is the size of a wristwatch tucked into the left corner behind the steering wheel (you can switch the display on the LCD screen), while the option for connecting to an iPhone takes prime and primary placement in the center console screen.
