I could spend some time talking about the miracle anti-viral cure they are buzzing about, instant communication that allows people to track social changes real-time, or even the fact the flying cars are very nearly here.
No, instead I will point out the fact that the definitive reference of the English language, which is normally a 20 volume set that costs $1000 is available as a $13 phone app.
Yes, you can have the OED on your phone.
That's pretty amazing.
Now if you will excuse me, I have a dictionary to install...
*Edit* Blech. Someone pointed out that it may be dandy app but it is not in fact the OED. If you read the reviews below you will see although it is a big dictionary it is not the complete OED and has no link to the web back-end that house the 20 volumes online.
