    Rated 5 out of 5 by Bill535 from The Quality is worth the price. Quality and worth it. Use it in a business, very harsh conditions for a computer, and this one does the job. I did upgrade the keyboard and mouse to wireless. The touchscreen is great, and the display is clear. The power and sleek design is spot on.
