According to Kobo officials, the Jelly Bean update for the Kobo Arc tablet provides a number of advantages, including faster performance.
Other changes include:
• Google Now - delivers information according to the location, time of day, history and calendar events.
• Face unlock - improved to cater for different conditions and to require a blink to prove it's not a photo in front of the camera.
• Improved voice search
• New keyboard provides predictive typing and 'glide' operation (instead of tapping at the keys)
• Improved notifications - act directly on notifications; display more or less detail.
"With the latest Jelly Bean update, Kobo Arc becomes the perfect eReading companion that offers more with intelligent search recommendations, voice-to-text, and a highly responsive touch screen."
