Eladrin existed because WotC thought players were too dumb to understand the difference between two types of elves and that having wood elves and high elves was confusing. So they took the Elrond elves and made them eladrin and kept the Legolas elves as elves.
As reasons go it was pretty lame..
I'd separate high elves and eladrin. They're very different in concepts and lore, and eladrin in 4e never fit well with established grey elves, silvanesti, sun elves, etc.

No, they separated the civilized magic using elves from the earthy martial elves by making the former otherwordly fey.Straw man much? Isn't it to separate the otherwordly fey from the trad fantasy woods dwelling archers?
I agree it was a terrible fit to retcon the Eladrin to preexisting "high" elves.
(snip) A race that can teleport all day long would be DISTINCTLY DIFFERENT from other races in a gameplay setting. You could imagine a race that has no doors to their houses. Who put buildings in "impossible to reach" locations, etc.
A race that can teleport "1 per day" would still have mystical elements, and you might have the secret room that can only be accessed with a teleport. But their daily lives wouldn't strongly integrate that ability in.
(snip) I feel that if teleportation is available as a cantrip, it'll probably only be 5 or 10 feet and either an action or a move to cast.
I don't know why out of all the Fey-types in folklore and mythology, they've never actually used Sidhe as one of them. They've instead tried to preserve branding by using Eladrin instead.
But they've already mentioned that the Eladrin with types like Bralani, Ghaele, Tulani and Coure are back too. I know they existed in 4e in some form too, but they've generally only shared names with their 2e counterparts.

Don't forget, though, that an eladrin has to be able to see its destination when it teleports.
