First thing first, this thing is not small and light, it is extremely small and ridiculously light. I can't feel any difference in weight when it is plugged in. Even the package is minuscule. I don't think anybody is going to be able to spot it at the Apple Store when it gets there, that's how small the box is.
Now, on to more important matters: stability and sound quality. Connection-wise, it works as advertised. You plug it in, the blue light turns on immediately and you are ready to record on any audio App, from Garage Band to Skype, and, of course, on my all-time favorite, TwistedWave (the Tascam App is nice but there's nothing too fancy on it). The dock connector is long enough to fit securely in place but not long enough to satisfy bumper-case users: you'll have to take out the iPhone to plug the Tascam unit. Oh well.
I've tested on an iPad 2 and an iPhone 4S.
If you plug in some headphones you can monitor the input in real time, but beware: if you use a headset, the mic on the headset will be the input source and the Tascam unit will be ignored. This is clearly stated in the Instructions Manual that miraculously fits in the Lilliputian box.
And when you finally press Record, $79.99 (+ $1.60 for next day delivery at B&H!) suddenly looks like a fair price to pay: the sound quality is terrific, almost glorious. Audiophile tests will sure be made and people will complain about this and that, but from a standard user point of view, this absurdly tiny piece of hardware is going to put my Zoom H2n to rest (by rest I mean eBay). Stereo separation is impeccable and input volume control on the side is handy. If I'm forced to complain about something, I'd say the capsules are too sensitive: they captured a clock ticking on the wall 10 feet away from me. On their defense, Tascam probably threw some sort of windscreen inside the device because there's no popping effect when you talk to the mic a few inches away from your mouth. As expected, handling noise gets into the recording if you move your fingers on the iPhone while recording (which is a problem on most handheld recorders). All in all, this might be as good as it gets in terms of portability and quality. I'm sure the Sony PCM-M10 gives you a slightly better dynamic range, but nothing beats the outstanding versatility of the iPhone audio applications.
I haven't tried the limiter but I assume it will work as advertised. Tascam says in the box that the limiter allows anyone to record "live music, conferences and auto racing", which is a curious mix of activities and assumes the user has a pretty cool life.
You can charge while recording trough the USB port on the side. One final note, I'm really disappointed by the fact that Tascam chose a design that does not include a Line-In connection. Journalists like me feel totally let down. Let's now join in prayer for v2.0.
