Don´t underestimate a good MicroSD card. Use one with at least 128 gigabytes of storage, so it will last for a few years. Ideal for Android Smartphones and Tablets and a must have for us photographers out there.
Also super useful for the Nintendo Switch. You can still buy games on cartridges for the Switch, but some games need extra storage, and many games like Indie Games on Nintendo’s eShop are available only via download. Plug it in, forget about it, and download tons of games.
