That's... not how you make a new product popular and make tons of money. That's how you make a new product a niche product. That's how you kill a product.
Vendor lock-in is for when you have already acquired the mindshare. Users hate vendor lock-in.
To start out having vendor lock-in baked in you'll have to have such an incredibly amazing and useful new product -one that's in its own category- that users will disregard the lock-in for having no choice. The Lytro camera is not such an amazing product.
Mindshare is extremely valuable. Vendor lock-in is a tool for when your competition is rising, but it's very risky, as it may close your product to new customers while making your existing customers want to jump ship as soon as practicable. Vendor lock-in is very risky not just for the customer but also for the vendor.
