Patty as for marketing:
I think the marketing to the public is being done by the big boys. like ireport,ipod,iphone and there are smaller idog, icat, iskin products etc etc... and many many more...so im thinking kids are being trained to accept the i/e the e has lost a bit of ground in the current times but just takes a big player to start up a trend... you and me we just Ride the Wave ...
I like both i and e which one depends on the word attached.
