NoteSuite (formerly known as Projectbook) has just gone on sale for the cheapest it's ever been. We're talking Super Savings. Mega Savings, even. "So good it's entirely possible someone has lost their mind" savings. Okay I'm probably exaggerating a little, but it really hasn't ever been this cheap before.
You can grab the popular iPad to-do/annotation app off the App Store right now for a measly $0.99, down from $4.99.
