Get 'em while they're hot. Amazon has its Kindle e-book reader back on sale, finally following up on that 5.5 hours of stock available the first time around. Of course, that $399 pricetag isn't budging, so if you were looking for a cheaper way to get into this racket, you'll have to look elsewhere. Or just squint really hard and pretend those two nines are zeros.
