@kova4a "Well, your posts are pretty useless. The design is finalized and that's what battery it will use. If you don't like that just don't buy it. Obviously Fiio can't cater to the needs and wants of all consumers. And as far as the replaceable battery goes - that's something that decided they don't want to use. Just like apple has been doing it for years - do you go on apple forums ranting about the non-replaceable battery of all their products?"
kova4a - I don't have any idea what your problem is with me, but if my posts are "useless" then by *your* reasoning, this whole thread has become useless. Actually, if it's within forum rules for you to call my posts "useless", I've honestly read every word that you've just written, and because I won't get that time back in my life, may I now most truthfully return the lack of compliment: did you really say anything, that anyone here doesn't know already? So what does that say about what you've written?
To everyone else:
OTOH, I noticed that some people here, and you know who you are, appreciated my posts, and to them I thank you very much for supporting my submissions. I get it that some people simply don't understand or even care why a replaceable battery would be better for we consumers. I get it that some folk knew nothing about mp3 players before the ipod appeared with its proprietary battery. But I love digital audio, and very much enjoy listening to my X3, and the fact that one day its (& the X5's) battery will be worse than my 12 year old Rio PMP 500's, is something that I strongly needed to address. And maybe it's indeed too late to raise this, nonetheless I believe at this stage Fiio may either be contemplating the future direction of their DAP products, and I thought that if enough people raise objection to the fact that its battery cannot be replaced I'd hope that they might in future do the right thing.
And so, as I've mostly focused on the consumer side to this issue, here is something for Fiio: how about someday after releasing the X5 soon, for a reasonably higher price - another variant afterwards, with all the same excellent audiophile features, but one which includes an easily and affordable, swappable batteries? Because the latter will surely have more second hand value, you will surely and eventually sell far more new units of it! Let's not forget that the ipod, the world's most successful music player didn't win market share because of its battery - (nor for its sound quality - let's not forget!!) - so why do you need to follow the ipod's battery example?
Lastly, I considered what I rose to be within topic, and there are a number of things I've stated which weren't fully argued earlier in the thread.
Thank you again to those few of you who appreciated what I wrote. That some people appreciated my posts, made writing them worthwhile.
