Never used any of the standalone video SIP phones, but I've used plenty of standalone voice only SIP phones and in my experience for the money an N800/N810, even if you ignored all the other features from the tablet and used it just as a phone, is one of the best values out there in terms of features and pure quality/compatibility. If you've got a good codec setup/appropriate bandwidth, the echo cancellation on the tablets even for speakerphone is absolutely astounding. Now, maybe hardware voip phones have evolved a bit since the two wifi ones (a linksys and, oh forget now, another big named VOIP wifi phone company) that I had last year... but I'm not so sure. Look for another dedicated VOIP phone that offers speaker phone, video chat, bluetooth headset support, and the full range of codecs (including g729, etc) for the same sort of price points... then get one and compare the audio performance/quality with things like speaker phone. In a lot of the "resi/end user" devices you don't even come close; it's only when you start getting into the Cisco IP sets, or some of the other business/commercial units that the features start to match up... and often times they're much more difficult to find, setup, and update/upgrade in the future. Just my oppinion though based on my experiences...
