Logitech Cordless Desktop LX500 and LX700 Showdown

msftmichael writes "CoolTechZone reviews Logitech's latest LX500 and LX700 Cordless Desktop Duo products. The author discusses problems with software, compares and contrasts the two products, and talks about wireless technology in a very in-depth review. Here's a quote: "Both of the products we are reviewing use RF (Radio Frequency) receivers to communicate between the mouse and your computer. It operates on the 27 MHz frequency, which is good for short range communication through less than 2 physical barriers. At this relatively low frequency, interference can occur due to proximity to other electronic devices, which is why Logitech recommends that you keep the receiver 8 inches (20 cm) away from your monitor or computer. They also recommend against putting it on a metal surface, and for good reason. While on top of our steel computer case, we could not get the keyboard or mouse to communicate with the receiver."

      As far as cordless mice goes there are a few good reasons:

      -A cordless optical mouse can go anywhere. If someone wants to show you something using your computer, you don't have to get out of your seat. Just hand them the mouse and they can use it on their lap. It's also very useful for when you don't have a full desk area (like with a laptop), you can have makeshift mousing surfaces out of just about anything and not have to worry if the cord will reach.

      -A cordless mouse stays put when not in use. This doesn't seem like a big deal at first, but going back to mice with cords I can often notice a slight "drift" in the cursor when I take my hand off the mouse.

      -Along the same lines, a cordless mouse has no directional resistance. It's a tactile preference that I've been spoiled with. Cordless mice always feel tethered.

      -You don't have to unplug anything to clean it or check the laser.

      Batteries really aren't a problem if you get rechargables.

      I'm sure many of the same arguments can be made for wireless keyboards, but I wouldn't know because I use a laptop most of the time.

      If you ever decide that you do want to use those buttons.. you might want to look at 'hotkeys'. Not sure about the homepage, but it's an apt-get away in debian.

      Most of these fancy button keyboards generally end up mapping their special keys to specific keycodes in X. So all you have to do is trap those keycodes in X and map them to run a command of your choosing. Thankfully, hotkeys does most of the hard work for this (interfacing with X, binding to keycodes). All you have to do is give it an XML file describing what keycodes map to what keys.

      Hotkeys comes with pre-specified xml files for several keyboards, but I generally roll my own. You can use 'xev' and a corresponding terminal to grab the keycodes for the buttons you care about. The 'userdef' xml tag in the config file lets you map arbitrary keycodes to commands. I tend to structure it so that for every special button, hotkeys runs: /usr/local/bin/hotkeys-handler BUTTON-NAME.

      Then, I can just edit the hotkeys-handler script as I wish, and the changes are reflected immediately. Now, couple that with a couple of handy tools like the command line 'dcop' (I'm a kde user).. and 'osd_cat', and I can get some fancy shit going.

      For example, when I press the 'pause' button, hotkeys-handler runs a script that:
      checks the status of juk (kde jukebox), and if it's playing, pauses it using dcop. If juk is not playing, it checks the process list for any mpg123 or ogg123 processes owned by my user, and if one exists, it sends the process a SIGSTOP, and records the PID (the 'play' script uses the recorded pid to identify which process to send SIGCONT to). How's that for functionality? One-stop pause button. If it's playing on your computer, it gets paused :) (Well, if you use other apps for music playing as well, it's easy enough to extend the script to handle that, as long as the hooks exist for play/pause/stop/next/previous etc.)

      The play/pause/stop/next/previous buttons all check the current playing song, the current progress and display all that info using osd_cat.

      The only problem is volume up/down. Turns out that turning the knob a few clicks causes hotkeys_handler to get run about 5 times in a second, and the handler script's osd_cat that displays the volume bar gets run that many times, and the output gets a little bit messed up because all the osd_cats write on top of each other. I think I can fix this with some judicious SIGINTs and some basic IPC between the different instances of the pause scripts.

      Anyway.. there are TONS of options for these kinds of keyboards, especially if you know a little bit about programming and are willing to dig around. I love 'em.

Other than that, I don't have any complaints about it.

    I was originally skeptical about the battery life on the mouse, because it doesn't have any way to turn it off. It sits in my computer bag, constantly on from moving around in there. Even with that, the batteries typically lasts about a month before having to replace them (2 AA).

    Every now and then, Fry's will have them in stock for $79, but I have seen them on Overstock.com for $50, with $1 shipping. I think a lot of stores don't carry them because PCs with bluetooth aren't all that common. Most laptops that have bluetooth are Apple, and most Apple owners wouldn't want a Microsoft mouse, so it is a niche market for this mouse.

    Also, I think MS made a stupid mistake by including a bluetooth dongle in the package. Most people who are paying more for a bluetooth mouse already have a bluetooth receiver in their computer, and are paying the extra so they don't have to use an RF mouse that requires a dongle. They should skip the dongle, and lower their price some.

    Also, I just checked Overstock.com. Right now, they have the MS Bluetooth Desktop Elite for $79, or just the bluetooth mouse for $38 with $2 shipping.
