[Android Stick & Console RockChip based Computers] deadhp1:
I run armtvtech. I've also been into these dual core android tv sticks since they first came out. I had the ug802 before it was released, and made the ICS play store fix for it. I've compiled custom kernels for the UG802, MK808, and MK802 III to support 1080p, xbox controllers, touchscreens and other options.

So I've got some opinions on the different rockchip android devices available.

MK808

cons:

-no signal on some hdtv's

-65Mbps wifi maximum speed, wifi also tends to drop

pros:

-Can run the fastest out of all the rk3066 sticks I've tested.(custom kernel up to ~1500Mhz)

-Good build quality

-extra usb otg port

-can run custom kernels

MX1/MX2

cons:

-can only run at 1200Mhz max(no heatsink!)

-no kernel source for the mediatek wifi

-solder joints on the usb ports can be hit or miss

pros:

-built in bluetooth

-wifi actually works at 150Mbps

UG802(I have 3 of these left, gave away 2)

cons:

-wifi problems

-4gb flash

-1200mhz max(no heatsink)

pros:

-wifi can connect at 150mbps when it works

-decent build quality

-can run custom kernels

MK802 III

cons:

-1200mhz max(no heatsink)

pros:

-wifi up to 150Mbps

-decent build quality

-can run custom kernels

I actually own the above devices.

Out of all of them the MK808 is the fastest, but has the slowest wifi and a nasty no signal bug.

The MK802 III has great wifi while still being able to run custom kernels.

The MX1/MX2 has really good wifi, but doesn't have any source code for the wifi so there won't be any custom kernels for a bit.

Geekbuying has just released the MK808B. It's exactly the same as the MK808, but it now includes internal bluetooth!

They've got it for $56.99 which is a bit cheaper than the iMito sticks right now.

It's a bit of a trade off 65mbps(MK808B) wifi vs 150mbps wifi(iMito)....except when you figure in that you can run custom kernels.

Also it's unknown if the MK808B still has the no signal bug on some HDTVs.

I hear good things about the Minix Neo G4 and the uHost2, but I don't have any of those to test yet.

I'm currently testing an amazing new stick. The GK802.

It's based on the freescale i.mx6q quad core soc.

So far it has a couple of bugs, but it feels smoother than the rockchip sticks. It's brand new...so the bugs will get fixed.

The wifi can go to 150mbps.

The resolutions actually change when you select them.

Android boots off a removable internal micro sd card. I made a dd image of my card before I even booted it up.

The stock play store needed some xml files in order to have access to a lot of apps.

Rooting was pretty simple

Freescale supports linux with hardware acceleration, so I'm attempting to get it to boot. I just need to figure out the uboot settings.

It's a nice stick for the money. I'm really enjoying the experience considering that I'm pretty tired of all the rockchip sticks.

Another alternative stick that's coming out is the Droid Stick A2 from kimdecent. It looks like it's a re-badged ATV-120.

It's got the amlogic AML8726-MX dual core processor. I'm mostly interested in it because that processor should be able to support XBMC hardware decoding.

I've been trying to get a sample of the ATV-120 for months now.

I'm sure that there will be some Allwinner dual/quad core sticks coming out within the next 6 months. This world in general is moving pretty quickly. There's rumors of a quad core rockchip soc coming out, and of course there's a rumor of a 4412 based stick coming out.

Last and mostly least is the Cotton Candy....it's pretty much an overpriced flop. If they had been quicker to the market it would of been killer.

The only thing it has going for it is the use android on your laptop/computer thing. That's pretty much a custom vnc client set to autorun and connect to the Cotton Candy via usb.

I don't see why any of these other manufacturers can't make that work with their sticks and usb mass storage mode.

I can't Cotton Candy recommend it to anyone.
