There are other reasons for this. In addition to the fact most supermarket tomatoes are not vine ripened, most of them are genetically modified to improve shelf life and reduce resistance to disease.

For casual reading where I can read in only one direction(from the front to the back, no skipping around) a kindle or similar device is very enticing. However, what about when I read a textbook or a technical book? More often than not I am trying to connect several similar concepts and have a finger or two marking my place as I rapidly switch between sections. How can I do that on a electronic device?

Seriously, have you used Dreamweaver? dreamweaver is far from one of those point-and-click WYSIWYG website creators of the 90s.

But how much of an improvement will they be over fluorescent lights, which we already have at an affordable price?
