All I can tell you is that I've had a first gen HP Spectre for several years. Its reliable. I use it as my portable computer for work and it has travelled throughout the US and Europe with no performance issues. The only thing wrong with it is a key that is losing its silver color. The key works fine, but there is wear showing. I like my HP so much that I bought the latest gen for my daughter, the audio engineer. Her larger, more powerful Spectre is also well travelled and has held up well for 2 years.
