I have to throw my hat in and say palm and graffiti SUCK,
having said that I cannot officially compare rosetta (newton's HWR) with transcriber, since I dont have my new iPaq here yet.
There are several models of the newton floating around on ebay.
Newton OMP --> Original Newton
Newton 110 --> Next up after the OMP
Newton 120 --> Next after the 110, I think more RAM ? (also came in 2 versions, OS 1.3 and 2.0 version)
Newton 130 --> 120 with OS 2.0 and backlight
Newton 2000 --> Great model, OS 2.1, backlight, slightly bigger display? More resolution
newton 2100 --> Upgraded 2000. More RAM essentially.
My first newton was a 120 and the I upgraded to a 2100. If you just wanna play with it get a 120(~$50-$80). I had a 120 but needed more from it (I carry my newton EVERYWHERE!) so I got a 2100 (~$300). I love this device, great programs (have dictionaries and references on it, as well as games a comm tools, addresses and all the trimmin's

)
The newton was, and is a great device. I just wish more enthusiasts who knew about ciding would provide extensions to make it better

(like improving Ir for modern devices like cell phones and other PDAs)
Its one amazing machine! I highly recommend it! After using the palm you will be pleasently suprized at how something older than your palm can be lightyears better !
