Of all the traditional ebook readers that Amazon has produced, the Kindle Paperwhite has the least amount of buttons: just one, at the very bottom. There you'll find the on/off switch, the status light, and micro-USB port for charging with a PC. This is where in which the first serious omission is found: the lack of a headphone port. This means no text to speech functionality, which might be a flat out deal killer for some, if not many.
The reasoning for this is to keep the Paperwhite as light and small as possible; Amazon has already explained that the audio chip required, or even just a headphone jack, would compromise such goals.
The Paperwhite ships with a micro-USB cable (which is white, an odd choice since everything else is all black), so it can be charged by connecting with a computer. This is a bit inconvenient if you're traveling and don't have your laptop handy. Though Amazon does sell an AC adaptor for a reasonable $10, the "sold separately" attitude is a bit annoying.
Thankfully, the Paperwhite's battery performance lives up to the fine tradition that previous Kindles have established. Amazon claims that a single charge can last upwards of eight weeks, and with moderate use, the device can certainly hang in there. Various tests under an assortment of circumstances proved Amazon's jaw dropping claims to be true.
Though one does have to be mindful of usage to get peak performance. The new screen is quite sexy, but does take a toll on battery life, and so does keeping WiFi on. In the case of the latter, the solution might seem simple enough: just keep it off at most times, but that's easier said than done. For starters, many users might want to have their last read page synced across all their devices, so having a consistent connection is nice.
Getting to storage size, consumers may scoff at the Paperwhite's mere 2GB of storage. However, when you consider that, according to Amazon's estimates, that's enough room for 1,100 titles, we there's more than enough for the most avid of readers. Still, the last Kindle had 4GB, so this can be seen as something of a step backwards.
