I can and have rdp'd into my dev box with my phone. IT works. It isn't the best but it does work.
on vacation. I always take my tablet/work lappy that can rdp to my dev machine. I won't do it unless the world is basically on fire. But I have done it.
also, checking emails once a day for 15 minutes means that when I get back to work I don't have to spend a full day working thru them then. I quite often will check emails on vacation and then write the response that will only be sent once I am back from vacation. It gives the impression that I was unreachable without actually being so. and it teaches others to figure it out if they can. It works for me.
To err is human to really elephant it up you need a computer
Never needed it.
I don't bring it with me anymore, vacation is vacation.
One time it was suddenly really an issue that I was away for a week and my employer sent a replacement to my client (for four days, so useful!) and I spent some time on the phone telling my replacement where everything was.
And then there was that time when a coworker called me, which he never did, so my heart skipped a few beats before going into overdrive mode.
Called him back, wrong number, didn't even know he called me
