I can only remember 3 things right now:
1 Car technology, the real white headlights and car stereo with Bluetooth hands free for phones, that really make driving more safe.
2 Bluetooth headphones with touch controls, no more need to waste time looking for the right buttons to press.
3 High speed internet, allowing to watch streaming movies in real time easily like on TV, and overall lag free connection to internet in real time.
Do you remember anything else?
