If I was going to buy a Bluetooth keyboard to get around my crappy MBP one, is there one that you could recommend? I quite liked Apple’s previous keyboard design but don’t want to end up with merely another of the current flavor. Thanks.
It's quite easy and pretty inexpensive to get a used copy of the previous generation Apple Bluetooth Keyboard off eBay. They're a bit pricey if you want a new one, but they hold up pretty well so you should be able to score a pretty decent used one for a good price. They also fit very nicely over the top of the tbMBPs. There's just enough of a ledge from the keys to allow the rubber feet under the Apple Bluetooth Keyboard to catch and stay in place. You'll lose about 1 cm of your upper trackpad, but I didn't find that to be an issue.
There are also plenty of copycat keyboards of the Apple Bluetooth Keyboard out there. I haven't tried any of them so I can't make a recommendation.
