Stick with one naming scheme for laptops
Having used Dell laptops for a few years (and having lots of friends who use dells). They all seem to follow one basic idea when it comes to naming the different models
->Inspiron = Buget Laptops
->XPS = Performance Laptops
->Alienware = Extreme performance for gaming
But recently dell india has gotten rid of the entire XPS 15 & 17 line of laptops and decided to name the performance category of laptops Inspiron 15R & 17R (http://www.dell.com/in/p/inspiron-17r-se-7720/pd.aspx?c=in&cs=indhs1&l=en&s=dhs). A laptop costing INR 95000 ( 1800 $) is definitely not a budget laptop.
For lot of Dell users Inspiron always meant budget laptops and XPS always meant Performance laptops.
In practical terms, this took me a lot longer to find my new laptop since I opened the XPS (which only features ultrabooks now) tab by default in your website and found nothing there met my needs. I resisted opening the inspiron tab initially because of my eariler stated prejudice. An inspiron always made me picture a INR 30000 (550 $) laptop.
