Re: Spot on, ElReg.
"On the other hand, we might suggest that a phone which can't be carried in one's pocket hardly qualifies as a mobile phone at all in this day and age."
Why? It can be carried place to place and can make telephone calls. "Mobile phone" would seem to cover that.
"If it fits in a pocket comfortably it's a phone"
My cordless landline doesn't, and that's a phone.
I can quite understand some people don't like large phones, but arguing they're not phones is a little silly IMHO.
