I've never had issues when flying with any of my electronic. Just be sure they are powered down (not in stand-by) and they should be fine. I suspect that you were probably going to need a new laptop soon with your last one, just happened to be at the wrong time.
Only thing I'd suggest is make sure things are up to date and to try and mark your network connections as "Public" so that the OS doesn't open up firewalls and allow your computer info to be compromised.
Though, the best policy is to just not use it...just enjoy the vacation.
