Variety
Between the second-generation Kindle (unveiled in February) and its large-screen brother the Kindle DX (unveiled in May), Amazon had e-reader variety cornered: It was popular (unlike its competitors with lots of e-readers but little name recognition) and had a few versions already available.
Plastic Logic, for the moment, has little to go on but good word of mouth and product photos, seeing as its proprietary e-reader won't be released until later this year. But credit Sony, whose original e-reader became an Amazon also-ran, for blasting back to life with three new e-reading offerings, all announced this month: the Sony Digital Reader Pocket Edition, the Sony Digital Reader Touch Edition and the Sony Digital Reader Daily Edition (all pictured), the latter a higher-end Reader with touch-screen and 3G capability.
Advantage: Sony
