The problem with device convergence is that we are expecting too much from them. I've been using converged devices since the early days of Atom 02, HTC and Dopod phones... None of them were much good at anything. More novelty than usable phones especially. iPhone changed that but still has limitations.
My iPhone 5 is a damn good phone and email on the go client. And the array of apps is staggeringly useful. But is left behind by both my Walkman Z and especially my iBasso DX100 as a music source. My W4Rs sound great from both these DAPs but flat from my phone. You could mate your iPod with a DAC/Amp to get more from your W4Rs but you may as well get a decent DAP as stacking devices is just a pain. If you're going to carry both phone and decent amp may as well make them decent separates and enjoy the best of both.
Just a personal thought based on years of trial and error.
+1. I've had a dozen years of trial and error on my back.
Let me tell you a little about a day in my life in 2003. I remember spending $400-500 buying a bunch of items so that I can
1. record TV shows on my VCR (I'd forgotten why but it couldn't be done straight from my TV output)
2. let an app transcode this show (since I don't have Sony's $400? memory stick recorder)
3. Split the shows across 2, perhaps 3 memory sticks
4. watch on my Sony Clie.
I did all of that exactly once, just once - it was an episode of Waking the Dead. Anyway, my point is this: if I wanted to watch this crossdressing or w/e guy apparently drowning his family in a boat, now in 2013, while I'm on the move, it's clearly a lot easier and a lot cheaper. Regardless of who the enabling parties are, we've come to a point where the greater external environment has conspired to make it feasible and convenient to do so. I don't think we're quite at that spot yet where it's easy breezy to completely switch over to the mobile phone for our portable audio rigs. Every year we get closer but manufacturers are content to generally withhold their breakthrough, unleash a little every year and upsell their achievement by 1500%.
Ideally until we get to that aforementioned point, there's no reason to make a move. Yes, you can be happy earlier than that, whether by strapping the PHA-1 (great form factor for a murder weapon BTW) to your phone or going insanely high-end. But the "might as well" factor, as well as the law of diminishing returns, both loom big and hard, and that's worth considering to every single one of you who's reading this. Doing everything in your power is not necessarily the best policy, even if its drawbacks are few and inconsequential.
