I've got at least four trips abroad remaining this year (3 to EU, 1 to Asia) and I'll probably cancel them all if this goes full-bore.
A) I don't check bags. I don't even know what I would put my laptop in if I had to check it. I have a pretty sturdy foam thing I can slip into my backpack if I had to check, but I can't really "lock" my backpack in any secure manner. This is going to be a field day for malicious luggage handlers.
B) data security is a huge concern for a lot of companies. If you're halfway competent, it's not too hard to keep all your files on a USB thumb drive or in drop box and just wipe your laptop before crossing borders but for morons this is going to open up a huge corporate espionage risk.
C) most importantly, having to spend that much time in the airport is a huge turnoff to me.
BTW if you're into one-bag travel, this is what I use:
