He's basically correct-- but every time I have gotten annoyed with a
slipping drill bit in my cordless and done something to eliminate the
"problem", I have ended up with a broken drill bit. Think of the chuck
slippage as a safety feature. Most bits that are SUPPOSED to have large
amounts of torque applied to them (spade bits, hole saws, screwdriver bits,
etc) have flats on the shaft to eliminate the slipping. Such flats are
easily added to a bit that _ought_ to have them but doesn't.
The slippage used to annoy me quite a bit, until the trail of broken drill
bits I was leaving began to get my attention.
I vote for the keyless chuck.

If you are going to be drilling in heavy steel or masonry go for the
Jacobs Chuck. If you are just going to be doing some handywork and
woodwork, save yourself a lot of trouble and go for the keyless chuck.
The keyless chuck grips good and it is much simpler to use and no
chuck key to keep up with.

The keyless chuck on my Dewalt is a Jacobs chuck. I find that the key on
my other drill is so small it is difficult to really tighten down. Therefor,
I think I can tighten the keyless one a lot better. It's also a LOT more
convenient. I vote for the keyless.

Moreover, Bosch also uses the Jacobs keyless chuck. Additionally,
it is worth mentioning that the 1003VSR with the keyless chuck was
the comfortable winner in the last Fine Homebuilding mega-review of
3/8" VSR corded drills, about two years ago.
My DeWalt has a Jacobs keyless chuck, and it's fantastic...obviously
more convenient, and you can crank that sucker down quite tightly
with none of the pain of a conventional geared chuck. It's not like
you're shopping for a hammer-drill; go for it!

I've used a keyless electric drill for several years. It works well for
all normal home tasks. And it's a lot more convenient than using a key.

I've got a Milwaukee 1/2" Magnum that I bought with Milwaukee's keyless
chuck. Never did hold in high torque work. The Milwaukee service guys
said that was typical, and they promptly set me up with a keyed Jacobs
chuck -- performance has been great with the new chuck.
My Panasonic EY6205BC has a keyless chuck -- works great for those low
torque situations.
