I know lots of people hate it but taken in isolation it's okay. I found its aesthetics charming and its pace generally pretty chill. It wasn't good but it wasn't terrible. Low medium perhaps but I have comfortable memories of listening to an audiobook whilst playing it.
I assume it was made to upsell people to better CPUs. Celerons have always been awful.
That said, if Win7 came preinstalled then we're talking about different eras of Celeron, at least, I cannot imagine it would be as mediocre as a low-mid AMD CPU from 2004!
I always think of an ex of mine defending criticism of her craptop. "It was good for its time!" No, no it wasn't. It was built around a Celeron. It was built to be trash. It was ewaste with extra steps.
