There is no IR blaster, but ridiculously, Kitkat has native support for it. Sometimes I really don't understand Google; Nexus line is supposed to be a dev phone, so why they decided to cut down the IR blaster, when there is software for it, is a big mystery...

Soldered buttons are no-go too!

Soldered buttons??? Excuse me, but this is bullshit! It is a well-known fact, that those parts break easily. So, one would need to replace the WHOLE motherboard in case of button malfunction (at least, not everyone is familiar with soldering technique). Both thumbs down for such a poor design!
