Update: 2018 - Sometime around maybe March of this year, the mouse started fighting with me in earnest. I can still use the keyboard, but the mouse is completely unusable. I'll probably order this product or something very similar eventually, but I don't have a current need to. Overall feel like I got my money's worth out of it.
Update: Six years later, I've completely worn off two letters, and partly worn off six others, but the keyboard still works, every key, and the mouse is still working. I have had a slight trouble with the mouse off and on where it'll double click when I click once, or click while I'm dragging. It's been off and on, and at one point, I got a new mouse, only for this one to start behaving again. That was almost six months ago, and the logitech mouse has been fine since. No other problems, and I'm still overall pretty happy with the purchase. I wouldn't go back to wired again if at all possible. It's just so much easier to clean, and the feel is right for me.
This thing is perfect. A couple things:
The keys feel fine. I am used to a laptop keyboard and wanted something with a mostly flat, slim profile. Reviews mentioning weird dimpled keys made me nervous-- for keyboard and piano, I'm really picky about what I want to be touching for hours. This thing, however, is perfect, comfortable, and non-distracting. The backspace key and all bottom-row keys, particularly the spacebar, are slightly out-jogged and convex-curved. It's subtle and cozy. Typing is a smooth and comfortable experience, and the little palm and wrist rest at the bottom is just enough for me.
The wireless quality seems good. I wanted a wireless keyboard and mouse so that when I hook up my Casio piano keyboard to my computer via MIDI-to-USB, I can drag my typing keyboard over to my lap or wherever else without having to fiddle with wires. I have a -very- small, dense space. This was more than adequate. The receiver was plug-and-play, worked perfectly, and I was never left wondering how to configure anything about it. The set comes also with a wireless receiver extension cord. This is basically just a USB extension cord, so I use it for other devices. The mouse has a cute little hidey-spot for the receiver underneath, too.
The battery life is more than fine. I keep forgetting to turn the keyboard and mouse off, but I've yet to replace batteries. I recommend getting Sanyo Enerloop batteries when you eventually have to replace the ones that come with the set. Since I always have them around, I'm not worried about battery annoyance or cost.
What else? The packaging was great, and the products are attractive and easy to use. I haven't tried the custom-programmable function keys yet, but I'll update this review when I do.
I have no complaints. I love this product.

A year later..
I have owned a few different Logitech accessories over the years and loved them all. Have owned this keyboard and mouse set for over a year now and LOVE IT. Never had any problems with it. Functions as it should and does it well. Batteries last a long time - as advertised (but depending on actual use). The buttons on the keyboard are soft, precise and fairly quiet. The mouse controls feel very precise as well. The clicks are short and distinct and the scroll wheel feels smooth. There is an LED light on both the keyboard and the mouse that warns you when the batteries need replacement - very handy. The keyboard has an adjustable tilt by moving the rubberized feet. You can also stand it on it's side and let it stand at a 90-degree angle to give you more desktop space. The keyboard also seems to be spill-proof as it is has a few slots on the bottom for the liquid to drain through (see pictures). Range: I sometimes use this set with my TV while the PC (connected via long HDMI cable) they're connected to is in a room about 15 feet away and works without interruptions. Overall, a great set and a good price that lasts and is backed by a good brand! Go Logitech!
