I am in the market currently looking for a Windows 8 touch laptop. There are numerous options available like the Lenovo Yoga, Vaio Duo 11, Aspire S7, XPS12 but all these models have a lower configuration than I would like to have. I had finally shortlisted to buy the Dell New Inspiron 15z touch model which costs 1099$ but doesn't have a HD display. But it does have a dedicated 2GB Nvidia GPU. So which one is better? This Dell model or the HP Spectre XT TouchSmart Ultrabook 15t-4000 which costs more because of the screen but doesn't feature a dedicated GPU. Or are there other better choices?
