I would recommend the T420/T430 . Thinkpads T series have excellent keyboards, build quality and reliability. They usually last many years. I would just suggest you get a FullHD one, it will really help with your coding. On top of that, the T series , being an old generation laptop can still have its CPU upgraded further down the line. The MacBook air is really expensive for what it offers. It's basically a 2015 model, with an old generation processor and low resolution display: https://noteb.com/?model/model.php?conf=4423208233512210891&ex=USD https://noteb.com/?model/model.php?conf=4423208233512210891&... The Ideapad is not bad either for the price. It might get the job done but it's a low build quality laptop not meant to last. If you could get a Thinkpad T420 for $250, that's probably a better deal than $450 on a new IdeaPad.
