Why not trick out your fresh new board with some accessories? The Pi 2 is a big deal - a big, big deal. It has an upgraded ARMv7 multicore procssor and a full Gigabyte of RAM - meaning you're going to see ~2x the performance on processor-upgrade only and 4x on average for mutliple-core procssors. That's up to like 7.5x increase in speed without taking into account the 1 Gig of RAM.Should you be excited? Yes. Should you be so excited that you forget everything you need to get started? No.
