Wow, I just looked up a photo of this keyboard and it's actually a physical switch, not even a key. What an odd design decision.
Actually, the keyboard layout looks pretty odd in general. I could forgive the Insert key (maybe there actually exist people who use it), but is there anyone who needs dedicated Scroll Lock and Pause keys?
edit: actually, I guess Excel power users might use Scroll Lock? It still looks like a pretty odd layout to me regardless.
I'm so confused by your comment about scroll lock and pause. Have you never used a desktop keyboard? This is exactly what the 104 or 101 key standards since the 1980s or so include and always have for backward compatiblity. Every keyboard on the planet would have these if we only used desktops. But when laptops were introduced there was a compelling reason to compromise and remove keys. To this day I remain frustrated to death by the missing keys, most especially End and Home and the arrow keys. I need that functionality on a daily basis, and that need has not reduced in the twenty years since I went to mostly laptop usage.
Scroll lock usually only is important if used for something specific in a specific app. And pause, yeah, has fallen out of use. But it is mostly that laptops are now so common companies avoid assigning functions to keys no one has.
Even on desktops, smaller keyboards are better ergonomically (because they allow you to put your mouse closer).
Home, End, PgUp and PgDn can be accessed on most (all?) compact keyboards as Fn+Left, Fn+Right, Fn+Up and Fn+Down. I use those very frequently, to me they're actually more convenient than dedicated keys (because Fn is near Ctrl, Alt and Shift, which are also used for cursor manipulation).
I personally don't care for large ('inverted T') arrow keys, but there are certainly laptops (e.g. Lenovo's ThinkPad line) that offer large arrow keys if that's something you desire.
And even back in the '80s there existed various keyboard layouts (PC, Macintosh, Sun).
