All of the early bird specials are sold out, but an iStick can be still be grabbed for a discounted price through the Kickstarter. Retail price of the 8GB will be $129, but $79 will get you one if you decide to pledge. Prices and sizes go up from there, topping out at $299 for a 128GB stick. If you're feeling especially fancy, you can get a gold-colored aluminum stick, starting at $500.
They've since added stretch goals, and the two that have been met have insured Passcore/Password, Dropbox, OneDrive, and Google Drive integration. If the amount raised tops $1M, they'll add Airplay/Subtitle support in the integrated movie player as well as an API for third party apps.
