For me it is perfect; it allows me to do web dev and enough mobile dev to write 80% of what I need to write[0]. I also do embedded dev on it and dev for retro (z80) systems (which are quite similar). I have a USB wifi stick because the wifi driver for the built-in chip is horrible. With Debian there is plenty of software and I too use it for emulation to use PS1 (Crash!) and MSX games and software. Windows 95 runs fine on it which allows me to play Phantasmagoria and some other old games as well.
