I’m glad your keyboard is working out better for you. Mine is just so inconsistent, but part of that is the touchpad too. Maybe I would have a different opinion if I just disabled the touchpad completely (and if my tab-key would stop sticking).
But I do think it highlights one of the issues you’ll have with any low-cost machine — quality control. There just isn’t enough of a margin to assure a standard level of quality. Now, this is admittedly a pre-production batch, so perhaps some of these issues with quality will be worked out, but given the cost, I’m not too confident.
