Played around with the S8 at Best Buy for five minutes. Here are my quick-fire first impressions:

• overall aesthetic is best in market
• screen has much more subtle curve than I remembered in past edge-screen models, in a very good way
• screen is GLORIOUS; watching video is visually immersive
• speakers suck compared to iPhone 7's stereo speakers; dulls video-watching experience
• Iris Scanner not as practical as fingerprint for unlocking; requires phone at very specific angle and eyes at specific distance. For a feature that is used an average of 120 times per day to unlock the phone, this would be a persistent annoyance.
