CSS Input Type Selectors - Possible to have an “or” or “not” syntax?

If i have a HTML form with the following inputs:

 type="text" />
 type="password" />
 type="checkbox" />

I want to apply a style to all input's that are either type="text" or type="password".
Alternatively i would settle for all input's where type != "checkbox".
Seems i like to have to do this:

input[type='text'], input[type='password']
{
   // my css
}

Isn't there a way to do:

input[type='text',type='password']
{
   // my css
}

or

input[type!='checkbox']
{
   // my css
}

Had a look around, and it doesn't seem like there is a way to do this with a single CSS selector.
Not a big deal of course, but im just a curious cat.
Any ideas?
