Greetings. Like the title says, my trackpad for my 2011 MBA is getting wonky. Apple no longer makes the replacement part, and there are lots of options online, but I have no idea which are decent or not. So I'm writing to see if anyone recently replaced their trackpad from this era and how it worked out. IFixIt's directions look good, but they are also sold out of replacement trackpads for the moment. I would rather spend +/- $100 on a new trackpad than thousands for a whole new computer, when everything else works. Well, ok, if I can find a replacement trackpad, I'll do the battery at the same time. TIA!
