Hi Tony:
Welcome to Apple discussions. I have an 'older' Bluetooth keyboard and it works just fine. For about 20 bucks, I would buy the older one. I cannot see any difference in functionality. Incidentally, battery use is an issue that has been discussed in these forums at length. FWIW, I use 2650 mAH Duracell rechargeables and a 15 minute charger. I have a bunch of rechargeable batteries and I am never longer than 15 minutes from a full charge. Rechargeables do not have the battery life of Lithium ones, but I really do not care for the reasons I indicated above. Barry Comments are closed.
