Eweforia,
To be honest, I do not see many compelling reasons to upgrade the KF1 to KF2.
Actually, *I* would have a compelling reason, as I am living in Europe and the KF1 is not supported in Europe (appstore does not work etc., so I still have mine linked to
www.Amazon.com) but with the KF2 I could access the European appstore etc.
Nevertheless, if I decided to upgrade, I would most likely go for the HD version.
Best regards,
Andy
