Maybe you're not worried about megapixels or photo resolution, though. What are you, some kinda nerd? All you care about is convenience, and why carry a stupid camera around when you've already got a perfectly good iPad on you, right?
This should be obvious already, but in case you haven’t caught on: you shouldn’t actually be lugging your iPad around with you in the first place. Here's a fun fact: if you own an iPad, you've probably got an iPhone too, which means you've already got a superior camera in a much smaller package. Yes, Apple makes their iPads soooo thin and light these days, but you're still lugging around a relatively large, exceptionally expensive slab of metal and glass for no reason, other than to play 2048 in the bathroom at the Taj Mahal.
Whipping out an iPad (or even your phone, let's be honest) in an unfamiliar place automatically puts a target on your back, and that multi-functionality you love so much cuts both ways. If you’re carrying a cheap digital camera, not only do you have MUCH more room in your pockets, but if you get robbed (it happens), you’re only out one thing: a digital camera. If someone snatches your phone or oversized iPad on the streets of Bangkok, you’ve essentially lost multiple devices all at once.
