Asset - Additional Custom Fields data Types

Currently we have Single-line, Multi-line, and Pick List

I would like to see the following types added:

Check box (simple boolean value)
Examples:
Windows 7 Compliant? Yes/No
64-bit Compatible? Yes/No

Note: Currently, we do this via the Pick List type adding Yes, No items to the Pick List but a simple check box would suffice.
Multi-select pick list. (ie. Press CTRL-click to select multiple items
Example:
Compatible Platforms: Win95, Win98, WinXP, Vista, 7, Mac, Unix, etc..

Note: We would like to track a software's compatibility across the multiple operating system platforms out there. The Pick List only allows us to track one unless we create combo entries like: "Win9x/Vista/7" on one line.
Rename pick list to Combo Box or Drop-Down List
Note: If Multi-select is added, rename Pick List to Combo or Drop-down for proper naming convention.
