There are certain things that just don't really happen biologically speaking because they're too much of a pain in the kiester.
Sensory organs, for example, require a LOT of nerve interaction. And nerves are sensitive. Thus it's a really, REALLY good idea to always have as many sensory organs as near your brain as possible. Likewise, sensory organs are usually vulnerable spots that need protection... just like your brain. It's a good idea to keep all your vulnerable areas next to each other so they're easier to protect.
If you look among all the life we know about, you'll see that this is pretty much the way things work. There are creatures with eyes on the end of their limbs (like sea stars), but these are very primitive compared to the kinds of things we use (they just sense light more or less).
And the same really goes for a lot of things that require brain-power. The human brain consumes 30% of all the energy your body gets - needing extra brains just to do things is thus a not-insubstantial disadvantage! Limbs, for example, require brains to run, so most creatures have as few as they can get away with having (even the octopus generally only manipulates things with two of its 'arms', and the rest it can control only to a much lesser degree).
If you read up on exobiology (the branch of biology that theorizes what alien life might be like), you'll find that intelligent creatures almost have to be a lot like us: two manipulators (minimum for coordinated action), two legs (minimum for good movement - slithering like a snake is actually harder), two eyes (minimum for good depth perception), and so on. Having more than that leaves less brains for thinking!

Very difficult to walk or hold onto things without an extreme amount of discomfort.

Very different! We certainly wouldn't wear shoes or gloves. We would most definitely be more careful of what we pick up and how.

Sensory overload! Wouldn't we see everything like a kaleidoscope?
Stubbing your toe now is bad enough, but if you could see it coming...?!

We'd never get anything done nor walk anywhere nor wear shoes or gloves.
What a nightmarish vision!!!!

Wearing glasses would be a serious pain!

need for more eyedoctors. do you really think we would be able to see out of them? how often are you going to poke them?
