But they come with their own little USB adapters. Lol. dont trust any computer without bluetooth built-in from default, this is like asking if you want a notebook without wi-fi. Bluettoh mouses have the advantage that they dont use 1 USB port, as bluetooth is a hidden antena within the notebook.
Definition of arkose. : a sandstone characterized by feldspar fragments that is derived from granite or gneiss which has disintegrated rapidly.
So I'm hopeful of a good run, although Oliver Sherwood's ARKOSE looks the one to beat. Late Eocene sandstone exposed at the Medicine Pole Hills (MPH) in southwestern North Dakota (11 km south of Rhame) is a conglomeratic arkose that unconformably overlies the Paleocene Tongue River Formation (Fort Union Group).
