(edit: thanks mod!). Well, since I do not have any gph former devices beside the wiz, I will compare it with that (and the dingoo). And since I do not have any games on it, I will let someone else review that.
Analog Stick / Control Pad:
Caanoo - 7/10
Wiz - 3/10
Dingoo - 5/10
(The Caanoo analog stick is much better than expected. It is very sensitive and reliable, and not quite as crowded as the wiz. Although I personally like it, GPH could have added a directional pad as well (like the psp and upcoming 3DS).)
Shoulder Buttons:
Caanoo - 1/10
Wiz - 4/10
Dingoo - 5/10
(Well... They look nice, but they are just absolute pieces of junk. No sensitivity whatsoever.)
Other General Buttons:
Caanoo - 9/10
Wiz - 2/10
Dingoo - 4/10
(Such a great improvement externally. The buttons are absolutely amazing. From the power switch to the home button even to the new volume switch. GPH did a superb job (besides the bumpers).)
Screen Display:
Caanoo - 7/10
Wiz - 8/10
Dingoo - 4/10
(The Caanoo and the Wiz are basically the same.)
Screen:
Caanoo - 8/10
Wiz - 3/10
Dingoo - 2/10
(Wow! It's not an iphone sensitivity screen, but it sure is close. The screen just looks so beautiful and works well in most lighting conditions. It is not "flaky" like the wiz screen when you tap it (those who own a wiz will understand what I mean). Plus it has g-sensor! The Dingoo screen isn't touch oriented so... it scores poorly.)
Shell:
Caanoo - 10/10
Wiz - 3/10
Dingoo - 5/10
(It's PSP quality, just gonna let that speak for itself).
Ports For Adapters And USB:
Caanoo - 4/10
Wiz - 6/10
Dingoo - 4/10
(GPH put flaps over the adapters which can become annoying, especially if you have a wi-fi dongle or a charger plugged in most of the time. I never remember complaining about the Wiz's, although I wish it did have a USB port.)
Menu:
Caanoo - 8/10
Wiz - 5/10
Dingoo - 5/10
(What a great improvement. It could almost put Sony to shame... almost.)
Recommendation:
If you are interested in your first emulation device:
Caanoo - 8/10
Wiz - 6/10
Dingoo - 7/10
If you are ready to uprade your emulator device:
Caanoo - 6/10
Wiz - 3/10
Dingoo - 1/10
Let me tell you now, I LOVE the Wiz (and the dingoo is okay). I would have never rated it so bad if I had never seen the Caanoo. It is worth the upgrade just for the feel and quality of the build (even though software is not an improvement). If you have a dingoo... time to throw that thing out the window. It is useless now, the wiz had better hardware than the dingoo, but didn't feel as good while playing. The Caanoo trounces the external feel and internal capabilities of the dingoo (and yes, I own a dingoo as well). GPH is starting to grow there company, promote more community support, and sells their own games (whereas dingoo is basically good as dead). They have the best chance out of any small time videogame company to make it somewhere in the world.
