Over the years, I have learned one important thing: geeks love numbers. They worship numbers. They pretend that numbers are everything that matters.
They are wrong.
The most important factor in how well a tool performs is not how many amps in the motor, or how fast it cuts, or drills or any of those measurements so beloved of comparisons in a magazine article.
The most important factor is how well it fits in the hand.
If the tool is too heavy, or too slick, or the grip is too big or too small... those are the most important factors. If it feels good, it will be easier to use. Only then can the other numbers, engineering data or price get into the discussion.
Computers have the same problem: it doesn't matter how good the CPU, or how fast the x Gigs of RAM work or any of the peripherals... use the keyboard. If you cannot use the keyboard easily (as is the case with this particular machine I"m typing on) then it's more of a hindrance than a help.
90 percent of the purchase decision must be how well it fits in the hand and everything else is secondary.
