Automated notices of firmware updates and the ability to download them directly to the tablet via the Wi-Fi connection helps make sure that customers have the latest technology available.
To make sure my Wi-Fi wasn't faulty, I tried some of the same sites, in the same spot, on an iPhone, an Android phone and even an older Samsung Windows Phone.
Now Facebook and Twitter do offer that kind of secure service - but it's not the default option, so users have to switch it on if they want to be sure that their use of those sites is private when they are in a public wi-fi hotspot.
