Openstax, a free textbook provider, will have online homework support. Look for roll outs over the next few years.
ALEKS is better tied to courses. There are not huge resource lists when a student wants help on a problem.
Hawkes finally has an online product. They may be worth considering again.
Some Pearson titles (Tobey/Slater/Blair) have iPad instruction. It doesn’t look ready for prime time, but may be soon.
Casio still has better calculators at a lower price than TI. We probably still won’t adopt them.
