Not sure how I could've missed it earlier but PalmAddict's Andrew Davis wrote a very complete review on the OQO model 01+ (http://www.oqo.com/), a device that doesn't exactly fit the description of a handheld nor that of a notebook device. The review, which is composed of (http://palmaddict.typepad.com/palmaddicts/2005/12/is_that_an_mp3_.html) three (http://palmaddict.typepad.com/palmaddicts/2005/12/the_evolutionar.html) parts (http://palmaddict.typepad.com/palmaddicts/2005/12/oqo_review_part.html), concludes:

All in all, in my opinion the OQO rocks! I love it. I now have an OQO in one pocket and my Treo 650 in the other. I have the utmost in portability and have internet access, my documents, and programs, etc with me all the time. I couldn't be happier... well, at least not til they come out with a better version of each. :) And that said, there are rumors of a 2nd generation device due out from OQO sometime this year. If it happens, I'll definitely be getting one and I'll donate my current OQO to a worthy Palm Addict reader... so keep watching PA on a daily basis! :)
