Thanks for the information, Dave.

The main thing that atrracted me to App Inventor was the ease with which one can use modules like BT, light sensor, accelerometer and so on, especially BT. How easy is it to use bluetooth with B4A? Have you used it?

At the price though, after the discount, it does look too tempting to pass.

BTW, as of September XX, I believe App Inventor is now hosted on the MIT server, and fully usable, so the accessibility should not be a problem, at least in the near future.

If you have used B4A, I would love to know your specific usage(s), as also about the learning curve, before I take the plunge.

Regards,

Anand
