Logitech Wireless Touch Keyboard K400 with Built-In Multi-Touch Touchpad

Got this on a great sale, not sure if I like it as much for the full $39.99 price.Small keys, reminds me of a small laptop keyboard (before everything went chicklet style). Backspace and Enter (CR) are pretty small but I can make do. Got my typing up pretty fast without much effort.Comes with 2 AA batteries. Thanks!What I REALLY wanted was a tiny wireless keyboard. This is as close as I could find which has the attached touchpad. I am not a fan of touchpads, but this is probably a positive for people wanting to use this from their couch on their HTPC.You can disable tap to click and gestures, which I did immediately. FN plus left click turns off tap to click, FN plus right click turns off gestures. Some people may like the gestures (like pinch to zoom etc) but I found it annoying when trying to use the trackpad like normal and it interpreted it as some other command.You cannot (or I have not found out how to) disable the touchpad entirely. However I think I can live with this since it's on the right and not under the keyboard where I would be hitting it constantly (like on my laptop).Nano receiver is very tiny, and it also includes a tiny extension if you need it to stick out some from the back of the computer. Installed in XP and 7 instantly without needing any drivers. If you want Setpoint you have to download it, they didn't include a CD in the box. Not a huge deal. I'm not likely to use any of the advanced features (key re-mapping, gesture settings, etc) that require Setpoint.Range seems good. Plugged into HTPC and works fine 10-13 feet away which is perfect. I didn't test farther than that.It doesn't interfere with any of my other wireless Logitech devices, which is a big plus. I also have a K800 and a mouse that use the unifying receiver and I was worried about crosstalk. No problems at all.So in short, I like it. Don't mistake it for a full sized keyboard, you may not want to crank out any novels on this thing. But if you need small footprint or to use in the living room, this is a winner.

The K400 is a wonderful compliment to HTPCs. I really can't image mine without it! Cheap and full functioned. Good size and sufficiently durable.FunctionPerfect! Has a dongle that will remain powered when the PC is sleeping. Any keyboard movement will wake up the PC making it ready for action. Ideal for HTPCs! I have an SSD drive so within about 5seconds of touching the keyboard, I'm ready to start watching something! Helps save a lot of energy to let my PC sleep and only wake when I want it to!There are many built in short cut buttons on the keyboard that are great for HTPCs, these include volume control, playback control. I understand that the new version of the k400r has removed these so if you want to use this for an HTPC I would recommend getting an original. They are also a bit cheaper.SizeAlmost perfect. This is actually a huge deal for me. I thought I wanted something really small like a real remote would be, but I tried the Lenovo and Logitech handheld keyboards and I was really disappointed with their ease of use(I don't have particularly large fingers either). This keyboard had just the right size for typing and yet isn't too big to be weird for a coffee table. There is probably a lot of personal preference built into "which size is right" but many people seem to agree that somewhere around the range of the k400 is about the right size. How else is it's popularity explained? Only thing I don't understand is the Van Halen design on the trackpad. (But I can live with that)DurabilityWhile not exactly built like a tank, this is durable enough for a couch area. I have accidentally sat on it a few times without issue. It probably could be a bit stronger but it is plenty durable.RangeThis is the only area that I've had some issues with. I have a mid-tower case placed on the floor next to my TV. The dongle is inserted in one of the front panel USB ports (about 2feet from the ground). I tend to place the keyboard in my lap when using from the couch. Sometimes I have my feet up on the edge of the couch so that they are blocking the line of sight to the receiver. At these timed the keyboard stops responding even though I'm only about 15 feet away from the receiver. Once I move my leg, it starts working again. I wish the receiver were more sensitive or the keyboard blaster stronger (perhaps adding a second blaster in the keyboard would solve the problem?)
