I believe these two models are being compared:http://www.bestbuy.ca/catalog/compare-result.aspx?ProductIds=10155022,10154697&returnPath=%257e%252fCatalog%252fProductTabCompareContent.aspx%253fSku%253d10154697%2526ItemsPerPage%253d15%2526CurrentItemIndex%253d1%2526CurrentPage%253d2%2526Sort%253dBrand%2526CurrentCategory%253d%2526IncludeParentProducts%253dfalse%2526SelectedProductIds%253d10154697%25252C10155022
Other than the slight differences in Optical Drive, Memory Card Reader, Type of Pointing Device, Number of Touchpad Buttons, USB 2.0 Ports, Loaded Software I don't see how the minuscule differences justify HP charging $240 CDN more than Acer's regular price of $529.99 CDN. The Acer is currently on sale for $449.99 CDN.
In terms of reliability the Acer has a better reliability record than HP.
I would recommend the Acer Aspire AS5742-7047 over the HP Pavilion DV6-3038CA.
