It seems like there are 4 levels of portability:
1: Backpacking up Everest. You're bringing the lightest possible thing, probably an aeropress or instant coffee.
2: Day hiking around trails or around town: Picopresso. It just seems to work and it's small enough to fit in a backpack with a hand grinder and thermos.
3: Regular camping, hotel rooms, parties, offices, events and anywhere with a table and a sink: The flair is awesome. They are really getting popular with renaissance fairs and popup coffee stands and you can just go anywhere with a table and water and make real espresso.
4: home and coffee shop: It's just not going anywhere ever, so buy a real espresso machine. Whether it's the flair or an olympia cremina or whatever floats your boat.
