I've been mining a few different Scrypt-based coins for the last few weeks and I have yet to hear of any Scrypt ASIC's that are currently in use. Doing a search I found a few examples of companies taking pre orders for future hardware but I haven't seen any specific dates for when that would be available. So far I've seen a few alt coins that are scrypt based but also use cgminer to gpu mine but that probably won't help you with your laptop. I'm also very interested in a such a device so hopefully I just haven't looked hard enough and there will be something out there now or in the near future.
