I've never heard "steak" pronounced anything other than "stake" (in English-speaking countries). In France I think they pronounce it "steck" and sometimes they spell it "steack".

"Mac off" - now that's funny.
How do you add -ing and -ed to those kinds of verbs by the way? "Mac-ing off", "mac'ing off" or "macking off"?

Interesting reading. We've been texting seriously for ten years and we still haven't figured it out.
"Texted" makes the most sense to me (and that's what I say). Someone mentioned verbs ending in triple consonant sounds; the nearest ones (other than "text") I can think of are "jinx" and "inch", and it seems we can all handle "jinxed" and "inched".
If we're going to say "text" as the past tense then logically we must also write "text". But wait! We all write "fifth" and "sixth" (some more examples of tricky consonant combinations) but they often come out like "fith" and "sickth". So we don't always say what we write.
