wow lots of us burned by the same thing apparently!
clever hardware suffers the burden of having lots of edge cases spread across a small customer base. going for dumb hardware that has lots of buyers is less exciting but statistically more likely to "just work".
for me: from now on, its either lenovo business laptops (which sell probably 10s of millions of enterprise users), or macs (which sell the same.)
volume > being clever
p.s. infact, even the lenovo TB docks are a bit shaky. ugh, more cleverness! i think sticking to their proprietary docks would have been the better play. with their volume, it would have made a better product.
