You do understand that you took that one line of my post entirely out of context, right? My whole point is that we don't HAVE to do an expensive hardware design and prototyping for a whole new product phase when we already have a perfectly functional set of plastics.IMHO that approach would be utter folly.IMHO: The key to making a 'Pandora 2' or 'Dragonbox' or 'Phred' is to keep the development costs as low as possible.
Money spent on prototyping and developing can lead to huge savings & a better product later on. One of the mistakes of the Pandora project was not to spend enough on these aspects. (If proper prototyping had been done with P1 then the problems of mass RMA's with the nubs & LCD cables could have been avoided etc.)
Lets look at a couple of potential but entirely hypothetical goals for the Dragonfly project :
1) Sell units at $500
2) Sell 10,000 units to cover design / development costs.
That would generate income of $5 million
To me a spend of $250,000 on software / driver development, Hardware design & prototyping would be entirely reasonable and would equate to $25 per unit sold. That amount does not really strike me as unreasonable.
From the Pandora 1 history, the motherboard design was knocked out pretty quickly. Yes there were some revisions, but overall, it wasn't what lead to a 2+ year wait. It was the plastics. Making them fit perfectly (top/bottom/screen fit) and mechanically (trigger buttons) was a constant tripping point resulting in weeks of back and forth delays.
The nubs caused an issue early on - but they're great now.
The keymat is -excellent-.
The battery is more than ample.
So why start over with a completely new set of design issues and revisions on -everything-?
Keep what's working (case plastics, design, battery, audio, keymat, nubs, stylus, SD slots, etc...). Replace what doesn't (WiFi?). Upgrade what is out of spec (motherboard, more RAM, CPU, video subsystem). It is a lot shorter road to travel than a complete redesign.
I don't think you could start from scratch and develop an entirely new system for $250K. More likely in the $500K+ range. I don't see that happening.
