Megapixels. More means sharper pictures.

I respectfully disagree. Or, at least, that is a misleading simplification of
how megapixels work.

Assuming that no cropping of the image is done, and you print the photo no
larger than 8x10, 3-4 megapixels is sufficient.

One would have to enlarge a photo to WALL POSTER-size to notice the difference
between 4 MP and 7 MP.

There ARE, however, advantages to more megapixels. Viewed on all but the
HUGEST computer display or printed to 4x6, there is NO visible difference
between the same shot taken by a 4 MP vs 7 MP camera.

More megapixels can also be considered "digital zoom". That is, you can
zoom-in to just a portion of the frame and save the photo there. This process
is accomplished by "shedding" pixels from outside the crop area.

7.1 megpixels is MORE than enough for the casual snapshooter.

Memory space. Mine came with 1 GB, though I can buy 1 GB or 2GB cards with
it.

The Canon model queried by the OP comes with a 16 MB (megabyte) card. That is
barely large enough to have fun the moment the box is opened before the
shutterbug is looking for a bigger card. A 1gb card is plenty. A 2gb might
be a little better. They have gotten so cheap lately that buying either one
shouldn't "hurt" too badly.

I shoot low resolution small pictures nearly all the time.

That is probably not a good idea. If the original photo is of a "small" size,
both in JPEG compression and "fine-ness", it can never be improved. This is
particularly important when one captures The Photo of a Lifetime or some,
other special occasion where enlarged prints are a possibility.

Using a computer and basic software, a large-size photo can be easily
downsized for emailing or other purposes where a high-resolution photo is not
required. If it starts out low-res, there's no making it better.

Disk space has become almost cheap, too. Shoot your photos at the highest
resolution and, if the disk fills-up, off-load the files to a spare drive and
start over.

The camera also takes silent movie clips.

The OP's queried camera takes movies up to 60 fps (frames-per-second) with
sound (probably monaural).

For B&H's $128 it sounds like a great camera.
