I wouldn't, I don't email myself URLs that I want to read, if anything, I would just save them Evernote, although I don't do that either. Also, Instapaper is doing that. iClooud takes care of uploading my iphone photos to all my devices, so the other use case is not too appealing either.

But hey, that's just me, maybe others would find that interesting! And it does sound like something you could do so quickly that would justify implementing even if you end up being the only user!
