I bought Dell inspiron with Intel Core i5-430M HDD 500 and 4 GB RAM, the performance of this laptop is very awesome. It has high battery backup inbuilt with 6 cells with clock speed is about 2.4 Ghz . This is very user friendly and I am very satisfied with this Product.
The only issue is the heating problem when we run 5-6 programs together but it will resolved only when I went to customer care service. The service is also really good they did not event charge anything for this.
