I was curious what wifi is useful for on a DSLR. I just watched a couple videos on youtube and it does seem pretty neat. With a Canon EOS app, you could use your smartphone to trigger the DSLR (useful for taking a photograph of yourself, group shots with you in it, etc). I also found it to be neat that almost instantly a photo taken with the DSLR could be sent to a smartphone, which you could then email to someone. So much for the days when I would photograph my DSLR's LCD screen with my smartphone and then send!
So I was curious what other cool things wifi can do. I initially thought it meant you could browse websites, check email, etc just like I can do on my smartphone. Can it do this, too?
