Conflicting Chromebooks

So guys, bit of a dilemma. Just turned 16 a few days ago. Ask for the Samsung chromebook ( ARM) and will be getting it soon. For as much of a Googler as I am, Google io slipped my mind. A new chrome book will be coming out. Better and with a comparable price I'm sure. Will my chromebook become obsolete? Will it be worth getting the one coming out in a few months? Why does God hate me? Etc etc.

Thanks in advance.
