Don't know much about mouse but have to buy one. Look at
the prices, optical mouse is more expansive than the
traditional roller-ball mouse. Is it better too? Does it
last longer?
I don't like optical mouse because they need batteries. If
the roller-ball mouse can do the work without batteries, why
not just buy roller-ball mouse?
Let's clarify a few things here: -
1) The plural of 'mouse' is 'mice' (though, in this instance, some would
say 'mouses' or 'pointing devices')
2) The word is 'expensive' - 'expansive' means 'capable of expanding'
amongst other things.
3) Where on /earth/ did you get the notion that optical = wireless?! I
had a wireless ball mouse years ago, just like I have a corded optical mouse
now.
4) You only don't like optical mice because you think they're all
wireless. A Google search will disprove that.
Let's see...Advantages of optical over ball mice: -
1) More accurate
2) Nothing to gum up, therefore never needs cleaning. A ball mouse worked
(and the past tense is deliberate, since I think they're pretty much
obsolete now) by moving the ball against four rollers (up/down and
left/right) and, the gunk and lint it picked up from the desk, would be
transferred to the rollers, therefore you would need to disassemble the unit
at regular intervals to remove the crud (I used to have to physically take
mine to pieces to remove all of it) and the ball would need washing in mild,
soapy, water.
3) Works on virtually any surface (except glass) no mouse mat required.
4) You can't buy anything other than optical these days
5) Funky red light (though these days other colourways are available)
Disadvantages....
Erm, none.
Now, if you were to ask for the advantages/disadvantages of corded vs
wireless
Advantages
1) Greater freedom (some can be used up to 50 feet away from the computer
(if your study is that big!)
2) In the case of Bluetooth (rather than plain old wireless) the ability
to use more than one device with the same receiver.
Disadvantages
1) Heavy - (the Logitech MX700 that I use weighs in at 170g. My old -
corded - MouseMan weighs 48g - nearly 4½ times as much.
2) Depending on what you buy, they munch batteries (unless you use
rechargeables - the 1800mAh that I use last 4 days on a charge. Logitech's
latest offering is said to last 30 days on a single charge, using a single
lithium ion cell).
3) Because they are so heavy, they are a major cause of RSI (if my MX700
didn't glide better over the desk than the MouseMan, I'd still be using the
MouseMan). I suffer from CTS, and I'm seriously thinking about changing back
to corded.
So, there you go, does that answer your question?
