Do the Pear Post-Its require a Registry to work and get viruses? Are the Apple Post-Its snotty and obnoxious? I don't know, I don't care. They are both pretty and will match your monitor nicely. [D-Bros via Mocoloco]
Apparently the Pear will take your notes but somehow fail frequently losing the notes you have written. The note will undoubtedly need to be erased several times, placed back in the stack of the other blank notes, taken out again and re-written. The impression I get is that the pear will be unreliable, so pay the extra few bucks and get the Apple.
