Incidentally that slide deck mentions the pi zero - which is still very cheap (the 2w is about $20 where I live), so I guess they're still honouring that even if their fancy one is pricy-ish.

Edit: I also found this article from before the original pi release https://hackaday.com/2011/05/06/miniature-pc-packs-a-big-pun...

The comments in that thread are very focused on the price point (many doubting it could hit $25, which it actually did reach) so I stand corrected; it was clearly part of both the marketing and the attraction.
