Well, I certainly can't let this thread go by...
So, to be impartial, I will not comment specifically about anything from our company (other than to include a few models in the round-ups below).
MP3 players are very much like cars in the sense that there are many to choose from, and each offer a different benefit to different people, and luckily for the consumers this particular category has matured to the point that there are a lot to choose from. Now, a quick summary to find out what's the best MP3 player out there for you (and a few options to consider):
Small HD Player:
* Apple iPod
* iRiver iHP series
* Samsung Napster
==> The benefits with a HD player are that you can take a *lot* of music with you, and depending on the size of drive you select, it is quite likely that you can take your entire music collection with you at any given time. The drawbacks are, that you have a bulky device (even at 6-8 ounces, which is what most of the above players weigh), it is much more susceptible to impact than other types of players, and frankly, for many people choosing music to listen to from thousands of songs isn't their bag.
Flash Memory Player:
* iRiver iFP series
* Rio
* Creative Labs Muvo
==> The benefits with a flash player are that the player weighs about 1/4 of a small HD player, there are no internal moving parts, and as such are much more capable of taking a jolt as well as being far easier (and more comfortable) to wear. They are great for workouts/running and offer many hours of music, which is more often than most people often get to the gym
CD MP3 Player:
* iRiver SlimX series
* RioVolt (getting hard to find)
* Sony/Panasonic (more of a checkbox MP3 support)
==> The benefits with a CD MP3 player are that you can still play all of the CDs you have, you can burn your own MP3 CDs for cheap (700MB discs for nearly free anymore), and you still get a all of the navigation and information benefits that compressed audio offer (browsing by song names, seeing artist/album information, etc). Certainly the drawback is that you still have a device at least as big as a CD, although many CD players in this category are just slightly bigger than a CD, and forget working out with one (or any CD player), regardless of skip protection, running with a CD player just isn't the best option.
Micro Storage Device:
* Apple Mini
* iRiver iGP series
* Creative Labs
* Rio Nitrus
==> The benefits here are that you have a device that is about 30-50% bigger than a flash player, but you get a lot more storage space for your $. The drawbacks are, that you still have a HD player, and while it is certainly smaller than the first batch of HD devices I listed, the internal workings are very much the same (granted because of the physics of a small drive, you get some factor of increased impact resistance with the microdrives). They can still be quite good for workouts, but they fall into a bit of a gray area for consumers. So the drawback here is basically, if you are looking for lots of storage, a bigger HD for a few bucks more is a good investment, if you are looking for a great workout piece, a flash player may be better for you, or one of these players may actually be just what you are looking for!
Now that I have that part out of the way, here is one other thing to consider when making an MP3 player purchase:
Will I be buying music online?
==> If the answer to this question is "yes", investigate this carefully. While iTunes offers a great service, if you buy an Apple device, you get to buy your music from iTunes. If you buy a device that supports Windows Media, you will have many more services to choose from, and this disparity will only increase over time.
Now, after all that, the best advice I can give anyone looking for an MP3 player, would again be like buying a car. Find what suits your needs, do some research on the products you find that meet those needs, and buy what's right for
you. If someone had a big family, and told you that you needed a Ford Excursion, because that's what they had and it was perfect for them, and you were shopping for an NSX instead, it's likely that you wouldn't see eye to eye, no matter how great they felt their Excursion really was (and might even be).
Compressed Audio, be it MP3, WMA, AAC, or even the goofy named OGG Vorbis, offers a lot of benefits to music fans. As you can see above, there are many different products that can suit your personal needs while still taking advantage of everything comrpessed audio can offer.
Enjoy. Whatever purchase you make will open up a new world of music enjoyment if you have never owned a compressed audio player before.
