This would be a no brainer for me. It was actually a no brainer when I purchased my IHP 120 a couple years ago, opposed to the Karma, which was my first choice actually, until I did more research and decided that the barage of complaints about HD deaths was too much of a risk for me.
I usually hear the same reply for this, which is "yeah, you visit a forum, and of course you're going to see more negative posts, because it's a support forum. That's very natural". Yeeah, whatever
Funny how over the past couple years of owning the iRiver, and being that I'm an admin on Mistic, home of iRiver stuff, I've seen virtually no similarly related problems on the IHP series DAP. I'll just confirm, I'm damned glad I chose the IHP. Especially now, for more than one reason:
Yes, ROCKbox kicks so much damned ass, it's not even funny. I won't even get into that though, because there's just too much ground to cover.
Stability. Hell yes, in spades.
Tweakable/Moddable ? Sheeet yeah. At the moment, the 20 gig ones are able to accept Toshiba 30 gig drives, which have been available for a while now. The replacement is extremely easy. I'm awaiting the Toshiba single platter 40 gig though...Should be soon.
The stock battery, which lasts an average of 15-16 hours, is also easily replaceable, with an available battery which boosts the life to approximately 26 hours. Hellz yeah.
So, as long as one keeps the body and electronics in good shape, I don't see a problem with having the thing for years and years to come.
Sound quality: IMO, it's fantastic. I don't use much EQ tweaking except for a 4 notch increase in bass when using my Sony V6's. With Optical IN and OUT ports, hooking it up to a nice pre amp, is dreamy.
What's more, is that not only is there database software available for it, but it shows up as an ordinary drive, for true drag and drop action. Something I personally couldn't live without.
