The Note5 is aimed at the productivity crowd with its pop out stylus and multitasking features. The S6 Edge+ is a great all around multimedia phone if you like big screens.
Samsung also has a unique program for current iPhone users to check out these phones through a promotion called the Ultimate Test Drive. For $1, Samsung will send you either model to try out – no strings attached – for 30 days. Then just return the phone. Here’s the catch – you have to sign up for the promotion using an iPhone.
