I agree. ideas are cheap (and they tend to change too). unless the idea requires a lot of biz dev (sales), I also fail to see the logic of a 50 50 split - unless money is involved
Do a 25-25 split (26 maybe, to have >50%) and hold the rest in the company so you don't lose control as you begin funding yourselves.
Startups (tech startups specifically) are a pass/fail course. You either all get money, or all get nothing (taken from one of PGs essays I'm sure). It's pointless to argue over equity except in order to keep control.
