They delivered the phone with delays, when people from first wave preorder got phones later than people could buy in shop, especially when they did not provide any info about this (they basically knew that it would happen) before people started to complain — it's failure to deliver properly and not hiccups.

Now i know that you all say it's crowdsfunding and delays can happen and they do not own us anything, but it's not true.
It's not donation or project without dates. And yes i can understand that there was delay and they told about it ahead and it's all good. But they decided to tell that they changed the screen for better one while I'm still not sure if there is screen to replace the original one, which is not nice thing (to delay because of problems is ok, but telling PR lies is not).
As well telling that there is delay ahead can be good only if there are updates or at least any info that follows, but for now passed moth and half and no info, people are not sure if they'll get it this month, next or maybe even September/August. And if there are hw problems or other problems, it can be understandable buy people if the info is shared(i do not ask for details, but at least some update like "we have hw problems with X and we can delay to 2 months, we'll update you as soon as we get info" followed by "we got new hw, but we need to change some OS parts coz of it and it would take minimum month"). But currently some company asked for money for product, they failed to deliver and there is no update, why, when it will be available or if it will be available. As well as it's maybe secret of what hw parts were changed but at the end you'll get tablet and you'll know what parts were replaced vs original specs, so no idea what and why to hide(i can accept explanation to this as well).
They had lack of communication and problems with that from 1st day, a lot of people got angry and tried to explain to them (including me, and even few blog posts, tweets, irc msgs got replies) and even if they had improved over time by giving more information, they still lack of giving important info and the info they provide is cherry-picked and sometimes is just PR with no actual info.
So they can use #poweredbypeople or whatever hash tag they use on twitter as much as they want, but if they do not provide at least what to expect for person who paid money for product after deadline, it's not acceptable.
It's like they think "deadline is passed anyway, no need to tell them when, they already did not get it in time anyway :P "
