Now, to the topic at hand.
I certainly feel that Apple could do much more to expand their MP3 market. Sure, it's going along very nicely, but there are things missing.
If you have new ideas for a specific model of iPod, post that below.
If you have an idea for a new iPod entirely, post that too!

I also ask of you to state what iPod you currently have, and what generation it is. Give some feedback, too, please

Personally, my favorite is the iPod Classic. It feels just like the original, with the scroll wheel that's been used for so long, it was on all the models except the Shuffle and the Touch at one point. Even the Mini, which has since been discontinued (replaced by the iPod Nano).
I mean, seriously. 160GB of storage!? That's insane. Not only that, but it's cheaper than some other iPod models (i.e. the iPod Touch).
Space has never and will never be an issue, thanks to the ability to hold 40,000 songs. I love it (Incidentally, it's also one of only 2 iPods Apple still produces to use the 30 pin cable, which has been around forever. Thus, I don't have to make sure I remember where exactly I put the cable, as I had to with my iPod Touch 5). I actually got my first iPod when I was losing my hearing. It was an iPod Mini, and I got a green one, as a birthday present. The logic behind it was that I would get to listen to music before I went deaf. Well, it's scientifically possible that the music prevented deafness, as the consistent ear stimulation kept cochlear function up, albeit depleting. Thus, I went from being expected to lose 100% of my hearing within 6 months to having gone 9 years now with my hearing still going strong...ish.... at 50%, which I can boost 40% more thanks to my hearing aids.
That, by the way, is also one of the reasons that I love Apple. It's very possible to make a decent argument that they saved my hearing.
Anyways, those are my experiences. Here are my ideas:
iPod Classic: Nothing needs to be changed here, it's perfect, especially with the CoverFlow option. Perhaps more colors?
iPod Touch: Better Siri, for sure. A possible 3G-errr 4G option, just for using the internet? That would truly make it an iPhone without the phone, albeit it might cause iPhone sales to drop noticeably.
iPod Nano: The iPod Nano 7th generation is a beautiful machine, but it needs a camera. It's understandable that video cameras and playback would be dropped, considering the iPod Nano 6th gen was essentially a 4th gen iPod Shuffle with a touch-screen, but now there's not really an excuse. You can watch video, but there needs to be a camera.
iPod Shuffle: I would absolutely love for there to be a way to visually SEE the playlists. I know that ruins the point of an iPod Shuffle, but it's just an iPod without a screen. Something without VoiceOver could be nice. Plus, the memory capacity is REALLY low, so that should be increased dramatically.
New iPod Idea:
iPod Tunes (Sounds weird? Hear me out). Obviously, iPods are known for just music playability, right? Right. The iPod revolutionized the portable music industry, changing it forever. But here's my idea for a new product.
Connectivity: On the top would be the fast lightning port, while on the bottom there would be an option to use the standard 30 pin connector cable. If that couldn't happen, it should at least come with an adapter. Compatibility would be nice.
Storage: Personally, I think it'd be nice if you could literally CHOOSE an amount (not just set amounts, but like you wanted 20 gigs instead of getting a 32 since it's better than the 16). This would probably only work online, but this would allow you to pay for what you could afford. You could get the best quality affordable. Want a 32GB? Can't afford it? Buy something less than 32, but more than 16. You choose. (Again, this wouldn't work in stores, but still...) The max limit? As much as could humanly be fit on a device of said size. (I wouldn't know the dimensions, so I imagine it could have the potential to go very high).
Interface: Personally, I think it should have wifi connectivity. I don't know what kind of shape it would have, but I would love to see an iPod Nano 5th generation-style comeback. I loved that thing, and it SCREAMED iPod. I also would love to see it completely customizable. That's right, Linux for iPod, haha. That would be AMAZING. It should also be able to connect to the iTunes Store to download songs right from there. It should also come with DOZENS of nifty apps to improve the listening experience.
Hardware: Like I said, an iPod Nano 5th-Gen-Reboot would be cool, but Apple should design the hardware for the most part. However, like said before, it should at least have an adapter for the Lighting connector so your old cables are still compatible. Also, it should have (wait for it) Wireless (Bluetooth or Wi-Fi) syncing and.....CHARGING. Wireless CHARGING. Imagine how useful that could be on ANY iDevice. Finally, it should come with GOOD headphones. (Not just EarPods, either. It would be nice to have over-the-ear Apple headphones, as there is such a market). Not Apple SuckBuds or Apple MediocrePods. Superior quality headphones that actually sound good AND fit in your ear, shipped in. You'll see why the better headphones would be necessary in a minute.
Killer Feature: Audio Quality. If possible, songs could be upscaled in quality (note: If possible) and you would be given an option to, for free, "revitalize" all the compatible songs on your playlist, giving you SUPERB audio quality, better than any on the market. For a device so centered around sound, it should logically have unrivaled sound quality, right?
Price Range: Personally, I was thinking $149.99 as a starting price. This is Apple, after all...Of course, it could go lower depending on how much memory is in it, as mentioned as a possible feature above.
(I apologize if this seems like I'm advertising Apple's products. I'm not.)
