Uh, yeah...
That malady goes by a couple of names... shinyitis is one... and GAS (Gear Acquisition Syndrome) another.
There's always something new and shiny coming down the pike, but once you have enough backups and backups of those, the disease may abate. May. Or may not!
Backups are, imo, essential. You don't want to be days / weeks / months into becoming an EX-smoker and have your one and only anything fail.
