As this thread seems to be a collection of Lemon-related stuff, not just loans, I should probably mention that I still haven't received any nuPlay prototype unit, nor any firm date when I should expect it to be shipped, and nor has anyone else I've spoken to about it (although I have had two or three erratic updates over the past couple of months saying it'll be soon).  There was very brief discussion on IRC of not sending the device since Lemon wanted to send it to someone who he felt would use it as he had intended, but that discussion concluded with sticking to the original plan of sending me a unit and my returning it once I'd seen it existed.

That being said, his offer of a nuPlay prototype unit was always a freebie with no deadline; on paper Lemon owes me nothing, ever, and I mention it only for its possible relevance to Lemon keeping his word.

Those are the facts; since others have offered opinions, I'll veer away from fact towards speculation and gut feeling now.

Some forlorn posts over on the nuPlay forum seem to be asking for hardware, software or updates on when either will appear, so it appears I'm not alone, but it's impossible to verify or falsify Lemon's claims that there are customers that have received units.

I considered investing in crypto.pm, and looked carefully into Lemon's background and past projects.  For reasons I'm unable to disclose for fear of litigation, when I asked him the first of the questions my research raised for me, I asked them publicly.  It seemed important for all to be able to see whether his replies were timely and to be able to prove he said something should it be necessary.  From the ensuing questions and responses, two things made me very uneasy: first, while his answers were always plausible they were never satisfactory for me personally since I never felt he gave any enough information on any question to make his answer either verifiable or falsifiable; second, I felt he tended to prefer to divert questions away from public forums towards e-mail (making assessment of timely response and whether e-mail ever got replied to much more difficult).

I have many other more specific doubts, but since (1) I'm not sure I'd get any reply, (2) I don't expect any answers that I'd consider verifiable/falsifiable and (3) Lemon has indicated a readiness to employ litigation (I don't know whether he would or could, but if so it'd be prohibitively costly to defend whatever the outcome), suffice it to say I'd strongly advise anyone considering dealing with Lemon to perform very thorough research on him and his past projects first.  I feel obliged to add that the same is true of any stranger on the Internet you're considering sending money to.
