Well i'm not saying caanoo is better,it's impossible caanoo will be better than pandora.
I can say one thing the case and buttons are well made and screen is good quality too.
The caanoo can play many systems full speed inc. mame,picodrive,snes,gngeo,neo geo cd,psx (some games are slow),gpsp and many others plus it has homebrew games audio race,battle jewels can be played with touch screen,caanoo can play movies,music,photos,ebook,flash games,has high speed port controller can be connected straightaway.
The usb peripherals can be connected such as controllers,fan,usb hub,mouse,keyboard can be used for some apps and also has tv out it'd good quality on tv but has border because of low resolution screen,the system can do alot for the price you pay for it,i got my caanoo for only £77.50.
This is the cheapest handheld system ever,which can do more than 3ds,dsi-xl,pspgo,if not the pandora.
