Title, basically.
The new magus archetype offers quite a bit of versatility compared to the regular magus, so what kind of tricks does everyone think you could do?
For example, at early levels you could still have a regular weapon in order to use TWF and to avoid expending spells, and if you end up wanting to use spell combat, you can as a free action dismiss your psychic weapon and then go into spell combat.
Because psychic spellcasters don't suffer arcane spell failure, you could in later levels do TWF with a sword and shield style and still get spell combat.
In much later levels, you could use two handed reach weapons for a great amount of battlefield control in spell combat and spellstrike with a reach weapon.
