I have a 15" rMBP purchased right after they launched and have been having an issue where for no reason, the keyboard will just quit recognizing my typing. It will pick up like every fifth letter I type. Now, I type fast, but not that fast! Not only is it annoying, but it's a huge problem as I'm a journalist, and it's awful when it happens in the middle of me taking notes. Usually, if I just stop for a minute, it will fix itself. A restart will also fix it, but doesn't seem to be necessary. I've had it happen both in Microsoft Word and in Evernote, so it's not program specific. Any suggestions on what could be the issue? Is it a known issue? I'm under warranty (and plan to purchase AppleCare), so I can get it fixed, but it's irritating that I'll have to lose my computer to do so.
