My questions on the canon, I can't find a way to put the date on te front of the pictures?
The Canon S5 does not have that option. It is a matter of personal taste, but I would personally fear the risk of crippling pictures with this. However, each of your files is appended with EXIF data. These are "metadata" that include the date, time, camera model, even focal length, exposure time and aperture. And there are some free softwares out there that will pull the date out of the EXIF data and write it on your picture.
Also you can zoom in on a picture you took but there is no way to crop it on the camera like there was on my V1
If the S5 is like my S2, you can edit movies, but not really pictures, on the camera. However, I know that you can apply MyColors effects when reviewing pictures, so it's possible that you can crop also. Your camera manual would be the best place to find this information

I am so used to being able to look at the pictures on the computer and checking the dates from the picture as to when an event occured.
If that is your only reason for printing date stamps on your pictures, then do not worry : almost every image viewing software will display the EXIF data if you want it to, and Windows will show the basics of EXIF data if you place your mouse over an image file.
Have fun with the S5! It's a great camera.
