Q10 air from Mobilkom Austria

Just received a Q10 air for testing purposes. It is a netbook with an Intel Atom CPU, 1 GB RAM (expandable to 2GB?), 160 GB 2,5" SATA hard drive (expandable to 500GB right now), WSVGA display (1024*600), WLAN, Bluetooth, webcam, Ethernet, 3 USB ports and last, but not least: a built in HSPA modem with 7.2 Mbps HSDPA downlink and 2Mbps HSUPA uplink capability. Size is 259*180*28.5mm, weight 1.5kg with the 3600mAhLithium-Polymer 6-cell battery. Cost is 696 Euros including the required 29 Euro/month data tariff (includes 5GB per month) from Mobilkom Austria for 24 months. Basically you pay the data tariff of 29€/month and get the netbook Q10 air for free.
P.S.: as it is a Atom based netbook I guess it should be quite easy to install MacOSX 10.5 instead of the supplied Windows XP. More on this soon.
