"I have had two Apple MacBook Pros with Bluetooth, location services (kinda like GPS, but not), and microphones. Of course, both of my iPhones have had these features too. However, I have never had any use for them. I have a bluetooth mouse, but I rarely use it because I have come to the realization that my trackpad works better."
Is not GPS for when one is traveling about the landscape and has a need for location based services?
Sort of pointless on a tablet Device limited to Wifi IMHO
and if you are tethered to a second 3g/4g phone then why not just run your GPS app on that device directly ??
Bluetooth is only needed for file transfer& wireless head phones
I personally would not use my 7 inch tablet as a walk around music player
there are smaller purpose built devices for that and much cheaper
And for file transfer I can get a USB to Micro USB cable for around $2 USD where I live.
