OS X support for it ended with El Capitan (2015). They were decent in their time, but are horribly outdated today. Https /The 2010 Macbook is the last of the plastic Macs. The only real advantage of the MBAs is slightly less weight and slightly lower cost. Apple does this to drive customers who need better color (artists, photographers, videographers) to their more expensive Macbook Pro line. The color gamut (saturation) on the MBA screens is also atrocious - about 50%-60% sRGB, the same as budget PC laptops. By comparison, Windows does do subpixel rendering, so fonts on even a 1024x768 screen look like they're 3072x768 resolution (provided the lines in the font are wider than a pixel). OS X does not do subpixel rendering of fonts, so the 1440x900 screen resolution ends up with (to my eye) really blurry text. Personally, if you're going to buy in the Macbook ecosphere, I'd recommend avoiding the MBAs and aiming for the MBPs.
Everymac is a good resource for comparing the specs of different year model Macs. Ebay sales for a 2015 model seem to be running around $500-$600. So while I would recommend upgrading from the 2010 Macbook, if you have your eye on the Macbook Air line I'd suggest just buying a 2015 or older model used instead of a "new 2017" model. But since it's Apple and a large portion of their userbase is not technically knowledgable and trusts Apple to watch out for them, Apple can rip them off this way. Any other company which tried to pull this off would see its sales evaporate to zero.

Apple didn't even bother to upgrade it to a 2016 or 2017 CPU. CPU (2.5 GHz to 2.7 GHz with turbo boost). It's basically a minor refresh on the 2015 MBA, and not a very good one at that.
The "2017" Macbook Air is also a poor choice. If you do decide to upgrade the drive to a SSD, be aware that the interface is only SATA 2, and you need to be running El Capitan to have TRIM support. The 2010 Macbook is the last of the plastic Macs.
