The HD in Story HD comes from the display, which has a resolution of 768×1024. This compares favorably to most other eReaders; both the Kindle and the Nook have a resolution of 800×600. Readers will enjoy crisper text thanks to the higher pixel density.
Besides the display, the hardware in this new device is typical. An ARM processor powers the reader and WiFi support is standard. Traveling with the device should be no problem, as it weighs just 7.3 ounces and packs a battery that can power the device for up to six weeks on a charge.
What you won’t find, however, is a touchscreen. The Story HD instead uses a QWERTY keyboard and physical button interface. The decision not to include a touchscreen could be a deal-breaker for some consumers.
Integration with Google eBooks means it serves as the built-in bookstore for the device, just as Amazon serves the Kindle. Users will also be able to read books directly through WiFi without downloading them to the reader. This does not mean that the company has any intention of restricting access to the store from other devices and software , however. Its eBooks will still be compatible with various smartphones, tablets and most other readers.
