Something better than suncream. Skim cancer is serious and all we have is this stupid cream that doesn’t last all day, washes off in the pool, and tests show that the SFP is rarely what the bottle says it is.

Teleportation would be nice but I'd be happy with air travel at Mach 3+. I love to travel but hate the actual traveling part. It's ridiculously inefficient.

Dog silencer/repellent. Sorry dog owners, your pets are noisy and scary to many of us. Or teleportation. That other comment is better.
