Why I won't switch to the Canon EOS M

It's the same reason why I switched from the Olympus E-P1 to the Panasonic G2: I use reading glasses so a camera without a viewfinder is difficult to use. I was taking too many shots with the camera held at arm's length.

But the EOS M looks good. I like the fact that, unlike the Nikon 1, it can use APS-C size lenses without cropping. This means that DSLR owners can use the EOS M as a plug-n-play backup.
