[Shotimes] OT: Digital Camera ? - 3.1MP overkill for internet work?

[HomeboyNorm@aol.com]

Hey folks,

Would a 3.1 megapixtels camera be an overkill for some internet work such as 
Ebay, homepages, etc? 

Should I stay with a 2.0MP digital camera such as Canon's Powershot A40 for 
my type of usage, or to go with a 3.1MP one of the likes to a Kodak DX-4330?

Also, does anyone out here know what the maximum length of a movie I can 
shoot with either model?

Thanks, Norm the digital camera idiot (but learning fast)
