Waytools has said there will be some kind of 'extra' or freebie supplied with preordered Textblades and that the earlier the order the more significant the bonus gift.
For amusement I invite further speculation & suggestions on what this might be.
Merchandise - an obvious one, although personally I have not the slightest interest in any amount of caps, t-shirts or coffee mugs.
Personalization - Engraving or other custom identification on Textblade. Would be a nice touch, but most have indicated they wouldn't trade a single day of delay for this.
Spares - Additional Textblade components such as nanostands, nanochargers, alternative keycaps.
Discounts - Voucher for future purchase. If Textblade meets expectations I'd certainly be wanting one or two more units so I'd be pretty happy with something like this.
Priority Shipping - Everyone wants sooner. Mostly affects international orders as for us in Europe the slow option may take 3 weeks and priority costs $45 !
Mod kit - Assuming it's still viable for users to be popping key caps off and messing with the internals. Also presume this would have to be delivered at a later date.
Recognition - Easter egg based acknowledgement of early supporters embedded in the firmware or multimap. Not one I care about but some folks get a kick out of that kind of thing
A baby platypus - May cause problems with both supply and shipping.
