The one drawback to to the K760 is that it just isn't very mobile-friendly. Some people like to take their Apple keyboard on the go, and the smaller and lighter Apple Bluetooth Wireless Keyboard is about 30 percent lighter and smaller (0.7 pound vs. 1.1 pounds for the Logitech). That doesn't mean you can't tote the K760 around with you, but this is probably better suited for a more sedentary life in a home or office.
As far as ergonomics go, this model has the same Chiclet-style keys as the Apple Bluetooth Wireless keyboard and the look and feel of the keys are very similar, though not identical. I found the Logitech keys a tad stiffer and preferred Apple's keyboard a touch more, but the difference was minor. Of course, if you don't like this type of keyboard and its Chiclet-style keys, this probably isn't for you.
The price tag on the Logitech Wireless Solar Keyboard K760 is $79.99, which is the same list price as the K750's and only about $10 more than Apple's Bluetooth Wireless Keyboard. For more travel-centric folks, Logitech also makes the $50 Tablet Keyboard for iPad (the keyboard also comes in a model for Android tablets), which includes a stand for your tablet that doubles as a carrying case. That keyboard is more compact and doesn't have the solar-recharging feature.
In all, I liked this wireless Bluetooth keyboard a lot and wouldn't hesitate to recommend it. Yes, it's a little pricey, but the fact that you never have to change the battery will certainly save you some dough over the years and in the long run makes the K760 a better deal than Apple's Bluetooth Wireless Keyboard.
