Keyboard choice: M3800 and XPS not enough keys.

Dear All,

I've been using Dell laptops for 8 years. Generally the hardware combination drives my decision. I was very happy with my Dell XPS 15 (which had stunning display) despite a few flaws it was good. BUT I had to sell it because I couldn't adapt to the keyboard with not enough keys.

I really don't understand how people using Excel can go without Home, End, Page Up/Down buttons. 

Why does Dell continue to produce laptops for work (i.e. M3800) with a keyboard from a home line?
