How would you change Sprint's AIRAVE?

Now that Sprint's AIRAVE has been on sale (nationwide, that is) for nearly a month, we're curious to know if it has lived up to your expectations. We'll admit -- it definitely lived up to ours, but we can still think of a few things we'd like to see different. Would you too enjoy being able to use this thing abroad? Is the 3-call (simultaneous) limit too tight for you? Do you wish your EV-DO data was piped through this thing as well? Oh, and does the pricing scheme set well with you? Let us know just how you're enjoying (or not) that fresh new femtocell in comments below.
