A perfect screen for photographers, but the maximum resolution (4K) requires a good view The performance is like jai impression that I will keep this computer at least 10 years! It is fairly quiet except of the processor when running at full speed. Although the general conditions dacer stipulate that lon can not buy an extended warranty if lon has not bought the computer in the country where lon is domiciled, Acer Belgium confirmed my quune dAmazon.com invoice was valid for the Belgians. So I've bought lextension guarantee on the site dacer Belgium. Of course for that price, Acer had to make some concessions, some of which can irritate: - No DVD player. I bought an external jOperation that, in fact, very little. - The headset is on a single input jack - Internal battery - Inability to keep active the "NumLock" even after changing the register and not accessible from the BIOS; it always turns off after a suspend. - Lots of users have complained about the WiFi connection issues forums, and my copy was not an exception: a WiFi that worked on that once 10. Jai solved this by updating the drivers using the software DriverMax. In addition, the driver SD card reader was originally a Factory output disabled. I do not regret my purchase that deserves 5 stars if Acer corrected the most irritating some small flaws.
