Definitely take advantage of these programs when they're available in the future, I don't think this is the first time they've paid out to people who used the replacement program.
I don't think I'll need them. I'm switching to Linux.
Good luck with your Linux keyboard?
I'd imagine they're switching off Apple devices too. Perhaps to a manufacturer that doesn't rivet the keyboard to the top case making it stupidly hard for mere mortals to replace without replacing the whole top case. Like ThinkPads. I did that. Even stuck a Japanese keyboard in my W520 for like $30 for funsies and extra thumb keys.
I replaced a bunch of Dell laptop keyboards in 2006. Easy peasy.
