I'm going to attempt to answer as many questions about the Spark tablet as possible here. The questions I'll be answering are ones found in comments in my blog, on discussion sites around the Internet and that came in by email or irc. Let the fun begin!
Q: When can I buy one?
A: Pre-order registration will open early next week. This was one piece in the puzzle that was taking a bit longer than I had hoped for to come together, but it's finally slotted in and our distribution partner has got the necessary infrastructure settled. I'll lift the veil off of the pre-order and our distribution strategy when it goes live.
Q: When will Spark start shipping?
A: We expect to start shipping Sparks to you starting in May 2012.
