I generally don't enjoy full size keyboards since it forces the keyboard to be so far to the right it gets in the way of my mousepad.
Uhh... Just push it a little to the left? ... I don't understand the issue here.
Really! I never got that particular bit of fussiness either.
Okay, TKLs make sense if if you never use the number pad. I miss it right away, as I can no longer use Alt+#### codes to enter special characters like dashes, bullets, or accented letters (as IBM, in their wisdom, decided not to make them work with the regular number keys). But I realize that's not important to everyone. (Ha, I just used a dash, Alt+0151.) Some TKLs have embedded numpads that are activated when you press NumLock, so those are okay, but not all do.
Otherwise, changing your whole layout just so your mouse can be a bit closer? Even to the point of requiring you to hold modifiers to do things like moving your cursor, or jumping from one place in a line or document to another? My grandma would've called that "penny-wise and pound-foolish".
I realize there's a certain charm to using a keeb so small you can practically slip it into your shirt pocket. But yeesh, at the cost of making typing so laborious? Go figure.
Maybe it's just a fad. People see people with keebs like those, and they think that if they use them too, they'll be cool. But real coolness is independence from what others think and do, not copying them—so I've never gotten that, either. :?O
