Ziad,
Sick of TCI? How absurd.[not]
As far as RC2000's vs Prontos is concerned, being a dealer (and user) for both, I find the RC2000 mkII (or I) to be a hands down second class citizen. Perhaps like last years model I suppose, which really is what it is.
When the PC software releases for Pronto, it will no longer be any sort of a contest in my oppinion. The Pronto is far easier to program, fully graphic, more memory, and easy to read, regardless of lighting conditions. Have I missed anything?
My experience of our clients is that they generally like the power of the RC2000's but hate the difficulty in reading and operating. The Pronto on the other hand can actually have different menus available to different users if you'd like to do so.
Again, the PC software unlocks the full capability of Pronto far beyond the limitations available in the direct internal interface.
