The Dell Vostro line of laptops is reliable. I am reminded of its performance and stability as I type this on my own Dell Vostro 3500.
The laptop is super lightweight and easy to carry, and the battery life is long-lasting as well. My laptop comes with a 3-year warranty and customer support always address all my problems instantly. For heavy-duty functioning, I recommend buying another model as this one occasionally crashes. Starting the laptop is a slightly slower process, and sometimes it freezes and I have to end up restarting it, which can be frustrating. The sound quality is great, so listening to music and watching movies is always a blast.
Dell has some of the best devices that come with a full warranty, excellent customer support, and worth the money you spend on these items. But I highly recommend using another one that is faster and more stable.
