I'm definitely interested in hearing about people's experiences with these. I had pre-ordered one of their development phones last year, but gave up because of the constant delays.
I kept up with the dev list for awhile, but there were a lot of complaints about the hardware - battery life in particular, so I stopped paying attention.
The one thing I'm a bit weary about is their build environment. Last I checked they use OpenEmbedded, which to put it plainly, blew chunks last I tried to use it. After 48 hours of not sleeping I gave up and switched to OpenWRT's new buildroot-ng which I found significantly easier to use.
I hear you, I spent all WEEK fighting with OpenEmbedded. Painfully, it is better than LTIB. Actually there is a sub-set of OE called Poky that is really solid. OE's problem is that the packages vary in quality - primarily in their ability to compile on multiple platforms - Poky picks the betters ones and has fewer platforms, it works very well.
