2. Who knows what chemicals are left behind on the sticker.
4. Stickers get toss into the garbage. Or worse if you are eating on the run just littered.
There are no chemicals. The stickers are made of starch, are printed on with edible dyes and are stuck on the fruit with a thin layer of glucose. They are in fact perfectly edible and biodegradable. It's quite possible laser etching (by heating the fruit) will produce more dangerous compounds. Frankly, this isn't even a problem, people just like the lasers because they look cool.
Hate to say it, but I think Microsoft Office is a flat out better product than OpenOffice.org. It starts up faster, it has the whole macro system, it's just a lot more powerful.
What makes you think there isn't free-market competition right now? OpenOffice.org users can open MS files and save to the format as well. There are a few bugs, but those are true among Microsoft products too (open the same document in Word 97 or Word 2000 or Word 2003 and they look different). Open standards are great, but I highly doubt it will make a dent in Microsoft's hold of the office software market.
