If you don't see a reason to not have a camera, do you see a just as strong reason to have the camera?
Also, how many times do you use your phone's camera every day?
Would you rather have more capacity or a camera?
Camera. Definitely.
My cell phone is Net10. It is all I can afford. I pay $15 a month for minutes I don't use. My phone is the HIGH END MODEL that Net10 sells. A Motorola something something slider with a 1.3MP camera and MP3/AAC playback. No video. And no games unless you count the horrible Java crap they preloaded on it. No App Store either.
Some of us can't afford $80 a month for cell plans we don't need. If I could buy ala carte, where stuff was dolled out in slices for reasonable prices where I could get a lot of data, and a small amount of texting and minutes maybe. But you can't. They don't even allow the prepaid plans on the iPhone. AT&T wants you to pay more than you'll use because that's how they make money.
I want an iPod touch that has a camera that does video and photos so I don't have to use my cell phone. Why? Because my cell phone is specifically designed to NOT WORK with Macs. USB, Bluetooth, it includes both, but does not even announce its presense when connected to a Mac. I have to take the MicroSD card out, put it in its adapter, place that in my Garmin, plug my Garmin into my MacBook, browse the disk to find the photos and manually drag them to my desktop to get to them, then eject the disk, take the card out of the adapter and place it back in the phone. That's not intuition. That's something you should never have to do as an end user. Ever. If I had known about this little feature, I would have stuck with the phone I had.
I want a touch with all the stuff my phone doesn't do, or doesn't do well, because I don't want to carry around a half a dozen devices. I have a Kodak Z700. It is huge. I don't want to carry that around to take simple snapshots of silly crap I see throughout the day. A touch would be perfect for that. It also takes video, but do I want to carry that huge thing just for video? No.
The less devices I have to carry, the better. Since I can't afford to waste my money on an iPhone cell plan, a touch in conjunction with my $15/mo phone is my only option to get as much goodness of an iPhone as I can get.
I need a touch because I need a PDA like device. I want the WiFi for when I can use it. I want to be able to take notes, all that stuff. I'd much rather have a phone in my touch for the simplicity of being able to sync the photos and videos I take to my computer with one step. Instead of the half a dozen I have to put up with as it is.
My sisters have iPhone's. They also have three jobs to pay for their iPhone's.
