Yeh - this is indeed excellent news
Other beta programs Ive been on have been quite interesting and its allways great to get closer to the development of something you really like - but it definately aint for everyone.
If you need your gear to meet deadlines, gain income etc - then be warned - beta programs can be very frustrating under such contraints, also be real careful about patches created in betas - I should think with the TI you should be OK, but some stuff Ive been in beta's for, it was a case of write down on paper what you did so you can re-create the patch on the next beta update and finally the ship version
If you have the patience to live with you're gear being too buggy to make much use for a week at a time, and yet are willing to keep at it and keep poking it and can support yourself with some unpleasent side effects of beta code (trashed PC for example in a worst case scenario with beta audio drivers) - then definately apply, you will probably enjoy it if accepted
