Since I just bought an N810 last month, I think the answer is yes. I got mine because my aging Palm TX started having touch screen issues so I was looking for pocketability, wi-fi for light browsing, and a catalog of miscellaneous (and, ideally, free) apps. I went with the N810 rather than the N800 because my experience with the OQO 02 has convinced me that a little thumbboard is a great time saver.

The N810 excels in just about every area and I am certainly satisfied with my purchase.

As far as other alternatives, I find the N810 screen to be the lower limit of what I can use for surfing. The smartphones, including the N900 and the various Android phones, strike me as too small. You could spend a lot more and go with the Viliv S5 or the UMID M1. You'd get a much faster processor, a lot more storage, and a bigger screen. The downside will be their weight and battery life. Whether that's worth it to you, only you can say. You might also look at the announced Archos 5 Internet Tablet (the one that runs Android, not the one that is currently available for purchase). This would be the only similarly priced alternative to the N810 that I could see waiting for.
