I am inclined to agree with all you say, which makes me feel a bit awkward as I have just bought the NX300h. I have not driven the NX far yet, so I am still digesting the controls. The tech is amazing compared to my previous RX400h but I am doubting if, to be honest, it makes for a better driving experience. Apple / Android is great but I feel it is for the younger generation. Lexus do need to move on and update their cars with the latest tech to attract younger drivers. We "OLDIES" will shortly be no longer in the market for car - a mobility scooter possibly! I refuse, on safety grounds, to adjust the infotainment screen while driving. Fortunately the main driving controls are mostly accessed by buttons.
I feel I have bitten off more than I need to chew, regarding the tech in the NX.
Is there a huge difference in driving pleasure between my 25 year old LS400 and the newer NX? I fear, for me, the answer is no. So why did I buy it? The jury is out!
P.S. My wife loves it!
