One thing I want to see out of my current technology

I got to wondering today...why hasn't Apple developed an iPod with an SD slot?

Let's think about this for a few seconds, shall we?

Yes, the iPod memory is flash technology, and SD cards are also flash-based--wouldn't that be like doubling up on the same technology in one device? Well, yeah, but what's so wrong about that?

Think about it in this sense: You purchase an album on an SD card (some people out there think that might be a good route to go), and you want to put it on your iPod without having to go through the middle man of your computer and iTunes. Well, right now, it doesn't seem like you'd be able to do it (I welcome comments from anyone telling me I can, and how to accomplish that without cracking open my iPod). How awesome would it be to take that SD card you just bought and put it right into your iPod to give the new songs a (metaphorical) spin? Yes, at some point, if you want to transfer the album to your iPod for good, you can go through your computer and have it now in two spots. It could also offer the opportunity to "share" the music with someone else and possibly avoid all the copyright infringing--much like lending a CD to a friend (and, you know, assuming they aren't borrowing it to rip it). The same would work for videos, and would allow a person the chance to pop a card in and watch a video on their iPod and not have to worry about taking up precious space usually reserved for music (I know I try to keep my iPod for mostly music, maybe I'm an anomaly in that sense--I just don't know).

All I'm saying is that I think that this is a missed opportunity right now, and if Apple put an SD slot on an iPod, it could make the machines even more versatile, and could very possibly make my life even a little easier.

What are your thoughts? And what would you like to seen done to the iPod?
