Disclaimer: I'm not a spec-hound or of the mindset that anything less than flagship, top-shelf is garbage. I have modest needs in my devices. Please keep that in mind as I share some thoughts.
Here's a few hastily shot pics...
Here's a comparison of (from left to right):
iPhone 4, Aquos Crystal, Galaxy II Skyrocket, Lumia 520

The Aquos screen is wonderful. It is vibrant and sharp. Colors seemed pretty balanced.

I agree with YouTube reviewers who said that back looks like a band-aid texture.
photo of video playback:

Video Playback was smooth with terrific detail. Video filling virtually the entire device is something that needs to be seen to be believed. The chin bezel seems to disappear after watching the video for a few moments. This video was ripped from my DVD collection and encoded via Handbrake for an iPhone 4. The video is 2 hours 20 minutes and weighs in at 1GB.

Every device with a screen that I've owned has had a bezel. The Aquos Crystal stands out so much from that that it almost doesn't feel like it's real.... like it is some kind of prop in a SciFi movie.
The chamfered edges of the screen gives a futuristic look and makes holding it very comfortable. It is easy to forget that this thing has a 5" screen.
The style is right out of the late 70's/early 80's in that it reminds me of some of those futuristic looking stereo systems from Sharp, Sansui, etc. A little faux woodgrain would make the look complete.
Audio quality from the built-in speaker is pretty good... it certainly is much louder than I would play it if I were watching a youtube video.
Plugging in earbuds and activating the Harman Kardon Clari-Fi helps to add a depth and richness that I appreciated... especially pronounced when playing some 50's exotica/lounge.
The vibrating screen as the earpiece for the phone works surprisingly well. I have tinnitis so it can be difficult to hear certain frequencies, but I had no problem.
The phone is virtually all stock Android. There are only 2 Boost-specific icons baked into the ROM. The other 4 apps get downloaded and installed after activation. All 4 of which can be uninstalled like any other app.
Performance is very smooth in everything that I've tried. It is the fastest Android phone that I've owned.
For $150 no contract, I would recommend this to someone who is simply looking for nothing more than a portable media player. Pop in a 64GB microSD card and for under $200 you can have quite a PMP.
As a phone, I think it will do very well in replacing my 2.5 yr old iPhone 4.
I strongly encourage anyone interested in the Aquos to see it in person. The various reviews are all over the map and greatly influenced by the reviewers' particular tastes... more so than I think other devices.
