feedback needed regarding 3-4MP

I want to buy a 3-4 MP basic digital with the following specs:

ability to upload one picture at a time to my pc if need be via usb
simple/win os compatible software (I owned a Sony vid cam that had
horrible software!)
inexpensive

I will using the camera for basic family and fun pics, but in addition
I would like to use it for web design as well.

I'm planning on taking advantage of the after turkey day sales and
have found the following cameras at prices that are in my range:

Kodak 4mp CX6445
Kodak 4mp CX7300
Samsung 4mp Digimax 4010
Concord 4mp 4360z
DXG-308 3MP

I know Mega Pix are relevant when looking at digitals, but what other
things should I factor in to my decision? Any feedback and/or
suggestions would be appreciated.
