We've seen countless attempts to re-invent the Post-It note, but no one's ever really managed to improve on the basic design -- which might be why MIT's "Quickies" concept doesn't even try. The electronic note system is instead based around a digital pen and special pad, which saves your notes as you jot them down on RFID-embedded Post-Its. Software on your PC then does some quick OCR and, according to the inventors, "uses its understanding of the user's intentions, content, and the context of the notes to provide the user with reminders, alerts, messages, and just-in-time information." Since the database can also store location information, sticking the note on a book or other object allows you to locate it later using the RFID tag, and you can even have notes SMS'd to their recipients. Pretty wild -- but we're more impressed someone finally found a good use for all those digital pens out there. Check a video of the system in action after the break.

Rest assured, we've seen some seriously sophisticated takes on the famed Post-It Note, but Girton Labs may have the most ingenious twist of all. The Ixp-Note, which is listed as "currently in development," is little more than a recyclable, reusable Post-It with oodles of intelligence. The device relies on low-cost electronic circuit printing technology, enabling users to select a time / date via the printed scroll in which they'd like to be reminded of whatever they just jotted down on the highlighted strip. When the time comes, an alarm similar to that found in a musical greeting card will sound, jolting the memory of the note holder and potentially saving the day. As it stands, there's no telling how much each of these will cost, but considering that the battery should last at least a year, you won't have to have too many spares around, anyway.

Truth be told, Audiovox has already perfected the digital post-it note with the DPF711K, but if you're all about flexing that DIY muscle and giving everything your own personal touch, we've little doubt that you'll prefer this iteration. Granted, this isn't the simplest of projects we've come across, but if you can handle a fair amount of soldering and aren't too bad at following directions, you may actually be able to pull it off. Quite simply, the resulting product enables users to input text via fingertip onto the dark pad shown above, and whatever you scribble in appears on the makeshift post-it note. Hit up the read link for more details -- or, you know, just jot down a note to check it out later.

Yeah, it's true -- we've got a soft spot for quirky refrigerator magnets, so we're inclined to take favor with Audiovox's Digital Message Centers. As you can see above, the fridge-mountable units enable users to display photos for family to see, and folks can even record audio or video messages (on the DPF711K only) for others via the integrated camera / microphone. As if that wasn't snazzy enough, you can even tag messages to a calender for playback on specific dates, and we'd imagine the content would look fairly decent on the 7-inch 480 x 234 display. Think your kitchen's ready for it? You can grab the video-capable DPF711K for $199.99 or the audio-only DPF710K for $40 less.

Until the entirety of the corporate world finally comes around to modern utilities like Outlook reminders and Google Calendar, those little yellow Post-Its will continue to dominate desktops across the land. Apparently Sony Europe has chosen to facilitate this environmentally irresponsible practice, by adding a special panel for the increasingly-obsolete sticky notes below the screens on their new E series LCD monitors. The panel also boasts a "handy groove which is ideal for holding pens" so you'll never miss a message in case, you know, you forget you're sitting right in front of a computer. Both the 17-inch and 19-inch models max out at 1280 x 1024 resolution and sport an average response time of 8 milliseconds, so we'll be interested to see how many extra Euros a run-of-the-mill monitor costs when it has a piece of plastic slapped on the front that may or may not disable screen angle and height adjustability.
