That's a tough call. Sometimes first release of new tech has some challenges and you may not want to be an early adopter. 10 years is really long in terms of wireless tech. It depends on your risk tolerance ultimately, I guess.
You might do some research to see what chipset MR57 is using and setup a Google alert about it to stay on top of any progress or issues that unfold in the coming months. That could help inform a solid decision and I think I am going to do that now 😉
