A portable machine isn't any less portable if it's not "awesome". But I do think it is awesome. Yesterday, I was playing the Switch in my garden while lounging. The other day I saw someone playing it on the bus. Every day my colleague brings his to work and plays at his desk. People call it a handheld/portable because you can hold it in your hand while playing it and take it anywhere. I can't understand why anyone wouldn't qualify it as handheld/portable.Yes of course, the Switch can be handheld (held in hand, literally), just like the Wii U Gamepad. But it doesn't mean the Switch is an awesome portable console to play in the bus, just like how the Wii U Gamepad is useless without an actual Wii U near it.
Drawing from a product known for its portability, I take my laptop many places. When I'm at work, I dock it and have extra screens, a separate keyboard and a separate mouse. Just because I do this doesn't mean I stop describing it as portable.
Handheld: something you can use while held in your hand.
Portable: something you can continue to use when you take it somewhere else.
The Switch is a handheld/portable.
