Thanks for the questions...
Is there going to be a Nordic PC version? Does it have the ISO enter key?
It depends on how well the large version sells in the Nordic layout. If the big version does well, there's a good chance you'll see a tenkeyless model also.
Any plans of making a bluetooth mini tactile keyboard? Thanks.
No plans at the moment, but we will see how the demand is. If enough people want it, we'll do one.
Any details on the battery? It says it'll last about 6 months on one charge..
Is it replaceable? What is its expected life?
It's a 1,600 mAh Li-ion polymer battery. That's big enough to last you 6 to 12 months on a single charge.
It's not replaceable, but a battery that size should last as long as the keyboard. That's part of the reason we went with one so big. Rechargeable batteries degrade over time, on a percentage basis. Even after 5 years, you should still get around a month's worth of charge — which is what other keyboards' batteries give you when they're new.
Is there any input lag using bluetooth?
There's no perceptible lag. It uses Broadcom's latest chipset.
