I am fan of the Alienware, I bought Alienware m15 R2 when it was launched in Feb 2019 even when my Alienware 13R3 is still working very fine.
When I first read m15 R3 to be launched less than half year after R2, I was worry and a bit of regret.
To both m15 R2 and 13 R3 I have bought, first thing I do was upgraded them to 32 GB memory.
While major improvements are 30 percent improved cooling and 9th gen. CPU, R3 does not look smaller or lighter than R2, R3 even has less battery capacity than R2 which already not so much for gaming and:
SOLDERED RAM IS CERTAINLY THE DEAL BREAKER ! !
I bought Alienware for their philosophy of powerful and highly customizable for advanced users. Now I am not regret bought m15 R2 and even think I was lucky to bought R2.
If it is thicker, heavier and not for customization, why don't I just buy Razer Blade Pro instead?
I hope DELL / Alienware read our comment and do not repeat this in next generation of laptops.
