For the power and battery life it's lightweight enough. It is indeed noticably heavier than the latest 13" MBPs but it doesn't bother me at all. In fact all of my non-Appe workstation class laptops were even heavier and bigger with less battery life and more fan noise.
Remember that we the users were the ones that kept repeating Apple should stop making their devices thinner and thinner and should go back to the roots, give us our ports back, bring Magsafe back, increase battery life, and so on. Apple listened and made this in my opinion the best laptop that ever existed.
feels like I have an old Dell.
You might want to try that and report back - the old laptops I have around have creaky housings, the display hinges are loose and the display wobbles back and forth when typing, the keyboard has some flex (the 14" has essentially zero), the fan is noisy and if you look at the power cable the wrong way it stops charging, and if you accidentally get the cable caught somewhere it feels like it's gonna break the socket off the laptop.
