That's why some people (like me) switched to Dvorak.
Your sentence on Qwerty was 43 top, 21 middle and 12 bottom row keypresses.
On Dvorak, it's 24 top, 45 middle and just 7 bottom row characters, twice as good!
"ithout" is also entirely home-row, so you wouldn't need to bother with "w/o". The word demonstrates Dvorak's other feature nicely, hand alternation and outward-to-inwards flow:
without
,gkjsfk (Qwerty equivalent)
RLRRLLR
The letter pairs typed with the same hand go smaller-to-big finger, since "th" (Qwerty "kj") is much easier to type than "ht" ("jk") -- and "th" occurs about 7x as often in English as "ht".
