Amazon on Thursday quietly updated its Fire HD 10 tablet with a new building material and an additional storage option.

Amazon unveiled its Fire HD 10 last September alongside a slew of other hardware including a 4K-compatible Fire TV set-top box and the ultra-affordable Fire Tablet. Starting at $229.99, the Fire HD 10 packs a quad-core processor clocked at 1.5GHz, 1GB of RAM and a 10.1-inch IPS LCD display with a resolution of 1,280 x 800.

The tablet has a four-star rating on Amazon although one of the chief complaints is its plastic rear shell which some say scratches easily, is prone to fingerprints and makes the device feel a bit cheap.

Today's refresh addresses those concerns, replacing the plastic shell with a silver aluminum chassis. Best yet, the aluminum variant is priced identically to the black and white plastic models.

The silver aluminum version is also offered with a 64GB storage option. The existing plastic Fire HD 10s are only available with 16GB or 32GB of local storage. Do note, however, that bumping up from the base 16GB to 64GB comes with a $60 price increase.

It's worth mentioning that all variants feature a microSD card reader, allowing you to add up to 128GB of additional storage. Seeing as you can get a 128GB microSD card for under $30, it'd be more economical to stick with the smaller 16GB Fire HD 10 and buy a memory card (assuming of course that an additional 128GB would sufficiently meet your needs).
