Earlier quoted context omitted.
I hate fn+arrow as an alternative to having real home/end/pgup/pgdown keys. It's probably the thing I hate most about my blade laptop.
Why? Do you feel similar about not having a "real" dedicated key to ctrl+c / ctrl+v ?
Because I came from a laptop that had home/end/pgup/pgdn and grew fully accustomed to those keys for keyboard navigation (which is my bread and butter these days).
The alternative was to get a 15" laptop, which is slightly too big for me, so I suffer in silence and occasionally bitch about it on forums.
