I regret selling mine in 2015 very much. it was perfect, I only had to replace the speaker because it suddenly went silent. but other this minor fault, I loved it. strangely enough the original air had more connectivity compared to the new one introduced in 2018 (with 2xtype-c ports in total and unlit apple logo).I still own the first design but with 128GB SSD (Mid 2009).
sure it just had a single usb2.0 (beautifully hidden in this flip down thingie on the right side) but it had dedicated micro-DVI and a separate magsafe1. so w/o any extra attachment it could be connected to a power source, a monitor and external keyboard/mouse at the same time. and the old L-shaped MagSafe connector was far less protruding than the later generations.
the original MacBook Air was a piece of art and truly innovative engineering.
