I'd like to update on the trackpad delay: Thanks to SimonOrJ (give him a thanks) I've found that microsoft now includes a setting to change the delay on trackpad usage after typing. I think this is new (or I might have totally been blind) because I looked for it before, but didn't find it. Under trackpad settings there is a dropdown menu for changing the delay length after typing. This is a great addition and lots of thank you microsoft for listening to our concerns.
I must say, however, that disabling it isn't the best solution because now we basically eliminate palmcheck, but it does fix the lag. It would be fantastic if you guys could release a more advanced palm checking algorithm that actually detects accidental taps and ignores it instead of just disabling the trackpad for a certain amount of time. This algorithm is more difficult to implement I understand, but a better solution to stop accidental taps while typing and also eliminate the delay after typing.
