I have an X1 Carbon thinkpad. It's not a problem at all to carry around---very light and thin. I have separate mouse+monitor setups in different places (e.g. office, home). So I just plug it in wherever I am. I keep the monitor and mouse plugs right there on the desk(s), so it takes two seconds to plug them in. I even have mulitple separate power adapters. I have one in my kitchen and another in my bedroom, for instance. They are literally 15 feet away. Totally worth the $70 or whatever since I can easily move back and forth multiple times a day. Carrying around and dealing with a power adapter is 60 to 70% of the hassle of carrying a laptop and that can mostly be eliminated. Oh, I also have a separate pair of headphones in each location AND one that always stays in my bookbag.
