I have to agree with the first poster. I bought my CT a week or two after it was first released in Nov. 2013.
The first Linux OS, Lubuntu was awful, most things didn't work, etc.
It's slowly gotten better and I check here regularly for OS's, but so far NONE of the operating systems seem to work completely, and I've tried at least 15 or 20 to date. There's always some issue - video playback, HDMI audio not working properly, posting here for questions and support takes days, weeks, or months for a reply.
After weeks of trying I posted my own Lubuntu setup instructions, which helped many, and then finally a week or two later the second OS was released.
For newbs to the Linux world, you too often get answers here that are for expert users: for instance, if and when you get a reply, it may be "edit this file /etc/blah/blah" or simply edit the conf file to say "xyx" - but without instructions that the full command would be something like "sudo nano /etc/blah/blah" and how exactly to do it, where as Rpi community is much better with all of this.
I have an Rpi B+ (14 months) and an Rpi 2 - quad core, 1gb, which is very nice - and possibly faster than the CT in many aspects... and... everything works and I ordered it 5 days after release - which was I think Feb 3, 2015. It arrived less than a week ago. It's up and running, wireless works, camera works, etc...
So far, of all the OS's, Cubieuntu I think was the best, but discontinued... Then it was Cubieez 1.0... then looking for 8 months nothing, and no one had posted that Cubieez 2.1 and 2.2 had been posted to cubieboard.org (in their own threads). You have to search through the threads to find it... but alas! with these two operating systems, my mouse is about 3/4th of an inch offset when trying to use it - what a pain! I've found nothing to correct it and no other posts here. HDMI audio is also not working, though it's the HDMI audio version of the OS. I've not gotten it to work yet.
When looking for solutions with the Rpi, it normally only takes seconds or minutes, and, of course, Rpi is made in England so the instructions are in clear, simple to understand - English, not Chinglish or broken english / Slovenian, Russian, Serbo-Croat, Spanish (no offense to any of these people), etc. Ja Precem malo Srpski.
I DO really like that the CT has bluetooth, SATA, Wifi, etc, built in, but, until Cubieez 2.1, I don't even think anyone had the bluetooth working well - which was released in like Sept. 2014, almost a year after I got my CT. I don't think this version is said to work well with BT either.
Then there was the awful stealing of this website by one of the mods, which took months to get things back to normal here again.
CT is a great product, and I'd buy the CB4 if it had SATA still, with that 8 core processor, it's probably really fun... but, when will an OS be out? A year, two years? Would we ever get one that really works?
Although I'm attempting to submerse myself in Linux and really learn it, having a community that was more proactive and helpful with creating a solid market for these great little computers would really add to the experience.
Right now the CT is not something I would ever give my 8 year-old to play with, but I have no hesitation at all with giving him either of the Rpi's.
