Feature:
Has so many features, I just got it in two days ago and I am learning them all. Really must spend some time with this thing, read the manual, etc...

Quality:
Very Very Sturdy and looks like it will last a while. The microphones look a tiny bit weak, but I am going to care and cherish this thing FOREVER!!!!

Value:
By far the best run for your money, has many features and you can actually record studio quality sound.

Desirability:
This thing is a Sexy Beast! :D Very appealing especially since I have a custom Red Windscreen. :D

Sound:
THE QUALITY IS SUPERBULICIOUS!!! The stock microphones are very good, but of course I am using the at4040, and the quality is just unbelievable! Studio Quality Recording!

Ease of Use:
Really easy to use. I gave it a 9 because it doesnt have a touch screen ;) hahaha

Support:
The best support is one you dont have to call! :D

Overall:
Overal it is awesome. I dont have time to explain just how great this thing is but I give it a 9.9 And coming from me, that is high praise.

Feature:
Nice accessories; I especially appreciate the plastic case. (It's not padded, however, so you may prefer putting it in a camera bag, but I like the plastic case because I can still fit it in a pocket.) The handle that lets you stick it in a mic clip is cute and will probably be appreciated by some, but I haven't needed that. (It would probably be good in a situation where you need to hold the H4n while recording, to minimize handling noise.)

Quality:
Seems to be very solid and looks great. I haven's seen an H4 "in person", but this is much nicer than my friend's H2.

Value:
This thing does a great job of recording and has features I don't see on more expensive models.

Sound:
I mainly use this for recording live bands at clubs, and for occasionally recording a song idea. The sound with the built-in mics is very good -- much better than I expected -- and it's even better with good external mics. (I seem to remember the H4 had some reports of noisy preamps for the external mics, but the H4n seems to be very quiet.) The best live-band recording I've done so far was with a borrowed pair of Rode NT5s in an ORTF pattern, so I intend to get a set of those soon. The best bass and guitar recordings I've done were with an SM-57 directly in front of the amp speaker and the amp's "aux amp" output plugged directly into the other jack, but the D.I. alone with added amp modeling and effects also works well. For acoustic guitar, the built-in mics aren't bad, but I like the sound I get with a pair of MXL 990s. But I'll probably continue using the built-in mics most of the time in clubs just because they are so convenient, and they sound reasonably good on live music. (You really need a room with good acoustics in the first place before better mics will do you much good, anyway.) I haven't yet had a chance to try it plugged directly into the house mixer, but judging from how well it does with mics, I'm guessing that will give you a very professional sounding live recording. Two things to watch for that screwed up my first recording in a small club, however: (1) Don't try to push the record level too close to 0 db. If you do, you'll probably get occasional clipping, which causes a nasty distortion that can't really be fixed even with "peak restoration" software. (My old UA-25 USB interface had an analog limiter that was much more forgiving, so I guess I got the bad habit of recording at high levels.) Leave yourself some room and aim for peaks no higher than about -6 db or even lower. The 24-bit sampling gives you plenty of depth, and with the noise level being fairly low you can normalize later (the H4n has that built in), or bring up the levels in your DAW. And (2), even though it's convenient to sit this on its little tripod on a table in a club, people walking by 3 or 4 feet in front of the mics can cause a proximity effect that changes the sound. So if you can't position yourself to avoid that, you'll want to get the mics up as high as you can. (The last place I went where I anticipated that because of the dance floor, I took a light-weight camera tripod, set it on the table without extending the legs and cranked up the center post as far as it would go, and it worked great.)

Ease of Use:
Ease of use is what I really love about this thing! I was doing live recording with a couple of large condensers (in separate cases), a UA-25 USB interface and a laptop computer, so I was lugging around a full backpack plus a mic stand and cables. It took me about 15 minutes to get set up -- after finding a wall outlet, that is -- get plugged in, booted and ready to record. This thing fits in my pocket as is ready to record in about 15 seconds, and rechargeable batteries will run it for hours. (And I'm getting better recordings,too, not the least reason being I no longer have Vista causing occasional pops and dropouts because it has something it thinks my computer should be doing instead of tending to the USB stream.) The screen is fairly large and backlit, which I understand is a considerable improvement over the H2 and H4. Most functions that are not controlled by the front buttons are controlled with a side-mounted Menu/Exit button and a scroll-and-click thumbwheel -- a lot like a Blackberry -- and I find it very easy to use after you learn your way around the menus. Record and playback levels are controlled with rockers on the sides. I think the Zoom engineers did a wonderful job of putting a LOT of features in this thing yet keeping it fairly easy to use. Did I mention I LOVE this thing?

Support:
Haven't needed it.

Overall:
I'm very happy with this because I can now do what I've always dreamed of -- getting good quality live recordings -- in an unbelievably portable and convenient package.
