You cannot use it directly - only with remote access. Probably the most simple solution is to use TV as Pi display.

Re: Is the RPi "just" an educational tool ?

Don't believe that 10 million Pi-s are sold for education purposes. At least 100,000 are doing real work.

Re: Make SD Card Read and Write Protected

I found this - hope it will run under Linux:

Note that the type of SD reader is important. Most cheap readers and some Laptop internal readers are connected over USB and cannot do this operation.

"Note that unlocking is done only for the current power session. As long as the PWD is not cleared, the card will be locked automatically on the next power up."

Re: Make SD Card Read and Write Protected

You can lock the card with password. But the problem is that SD protocol is not encrypted and it is easy to sniff and catch the password. Your software will be protected against non-expert users (hackers).

Don't agree. The low price is one of the major advantages of RPi. For $60 you can get x86 based second hand PC with HDD and compact case.

If the bluetooth connectivity is fundamental function, you cannot sell the device - and will need to ...
