actually Lenovo G505S has more freedom in some relations, if compared
to Chromebook R13 : for example, G505S does not require blobs for WiFi
and Bluetooth if you replace its' preinstalled Broadcom half size mini
PCI-e card with Atheros AR9462 (which has 2.4 GHz + 5 GHz + Bluetooth
and is top-of-the-line ath9k card) and its' price is just $8-$10 with
free shipping included ;) also there are some great technical
opportunities which chromebooks do not have - e.g. you could replace
WiFi mini pci-e card with double SATA ports RAID card, or you can
install 16 GB of RAM because G505S RAM is not soldered ! Still could
get G505S in good condition at many USA / European markets, e.g.
yesterday at eBay I saw G505S based at USA which costs just $95, also
UK-based in nearly mint condition ;) Also there are a lot of spare
parts available, which helps to ensure the long lifetime of this great
performance quad core laptop ( Chromebook is not even close at
performance, as far as I know )
