I was chatting with a camera guy and he was saying the average person does not need over 3.3 megapixels...he said save your money and there is no need for the 8.0 or 9.0 unless you plan on taking professional pics.
SO I would say the sony slim cam 5.0 should be plenty.
WATCH OUT for the online camera places...like if you google sony cams...they are LEECHES...yeah the camera looks cheap, but they will lie to you and say oh yeah it only comes with a 10min battery...but as long I have known no one would sell a product with a 10min battery...they try and sell you all these damn accesories...it is so shitty...I just told the guy to kiss my ass and cancel the order I will order from someone else.
any questions, just PM me.
