I'd be completely fine with this personally, the stereo speakers would be great and I use Bluetooth headphones so it wouldn't make a difference.
This reminds me of the PS Go for some reason. Everyone complained about Sony getting rid of the UMD reader, yet looking back it was an obvious move that pushed technology forward.
I could probably think of countless other examples like this over the last few years.
If you're upset about this, I don't think you've actually used modern Bluetooth heaphones. Give 'em a go.
