A fairly undocumented feature in the new iPod touch is the ability for the device to vibrate like the iPhone. It seems this vibrate function was designed with the deaf in mind, as its primary use is vibrating when a FaceTime is received. Apple markets FaceTime as the perfect way to have a phone call using sign language, and vibrate helps hard-of-hearing users know when a call is incoming.
No word on whether this vibrate function can be used in games and such like on iPhones but hopefully we’ll find that out soon. Another change in this year’s iPod touch is the absence of the plastic WiFi antenna strip. It will be interesting to see if it has any affect on signal strength.
