With an optical drive, a large screen, 0.5TB of storage and 4GB of RAM, Dell is positioning the new Inspiron 15Z right into the mainstream. For $749 (Core i3) and $799 (Core i5) you get a lot of laptop for your money. Options include touchscreen, BluRay, memory, SSD and discreet graphics but Ultrabook fans won’t be too impresses with the HD (“720p” – we’re assuming 1366×768 for Windows 8 compatibility) screen resolution.
