A shame, too. At least decent editors make this a tad easier. DrRacket, for example, binds lambda to Ctrl+\. Racket accepts both "lambda" and "λ" as the same thing, so it's up to personal preference.
I'm well aware of how DrRacket works; nonetheless, telling a newbie to type "lambda" will lead to typing, and telling them to type a lambda will lead to griping.
Also, the difficulty of typing lambdas also means that writing blogs about code, or documents, or emails, will require even more pain.
