I have today found on the Pyra's Wiki portal an useful chart which compares the specs between these devices: Pandora, Pyra, GPD Win, Gemini, Neo900 and Chaconne:


The Gpd Pocket is missing, I guess they didn't include it since it's more the size of a netbook rather than of a small clamshell. I must say it is the first time I hear about the Neo900 and the Chaconne; they both seem to be high specced devices (with a suitably high estimated price tag), still in the prototype stages, and for which it is still not clear when/if they will be released:


PS: and yes, as you can see I have disabled the automatic topic title capitalization, due to request. Actually it was a setting which automatically removed any shouting in the topic, i.e. words with all the letters uppercase.
