As above and 6GB memory not 4GB. The processor is fast enough that it will be good for 5+ years with a battery replacement midway, but the 4GB ram might end up hurting before that.
This is how I feel, 3 years later, after getting the 11 Pro in 2019. If I do upgrade this year, I'll give it to my dad, and he'll probably use it till it breaks :)
