That is
NOT a reason to suggest someone gets a wireless mouse.
Walk into any graphic design shop and you will see wired mice
PLUS Wacom tablets.
If you're seriously into your Photoshop / Illustrator, no mouse or trackball, wired or not is going to do you any good..... the pros' all use Wacom tablets for a reason.
And anyway, if you need a large sweep of the mouse, wired or not, then you've got your mouse calibrated wrong.
Note, I never suggested that this justified anything for somebody else. It was experienced based info.
and no, the mouse is not callibrated wrong if you're working with the fine edges in photoshop over a foot of screen travel and have the normal jitters after a beer
of course your mileage may vary
