The Acer Aspire 15 comes with a price tag of 499 dollars. It is powered by the advanced fourth-generation, Intel Core i5 processor. It packs in 4 GB RAM cache and has 500 GB hard drive. All of this is available in an exciting design that is evidently lighter than most other rival machines. However, the Aspire E1 does not have a touch screen. It runs on Windows 8 operating system, which holds a lot of promise. For a price of 499 dollars, the Acer Aspire is a lightweight and quite affordable 15-inch notebook that comes powered by the latest Intel processor. The Sony Vaio Pro 13 is quite light weight. Not weighing more than 2.4 pounds, this notebook from Sony is extremely portable. It is powered by a fourth-generation Intel Core i7 or i5 processor. It provides exceptional battery life and impressive performance on a daily basis. The 13.3-inch, 1080p touch screen looks vivid. Indeed, the Sony Vaio Pro 13 is priced competitively for the features it is offering. However, the Sony Vaio Pro does not have a removable battery, though the user can add an additional battery back up. It supports maximum memory capacity of a measly 8 GB. The Dell XPS 12 is another promising notebook. This is essentially a rotating-screen hybrid featuring high-resolution display screen and augmented battery life. The Dell XPS 12 is quite slim and easy to carry. One disappointing thing about it is the accelerometer which might provide erroneous results when the screen is flipped around. Also, the fan makes a lot of noise. The Dell XPS does not feature a HDMI output or a SD card slot. Acer Aspire 15 VsSony Viao Pro 13 Vs Dell Xps 12: What is your take?
