I am now the proud owner of both a Surface Pro 4, and a brand spanking new PowerHouse, Surface Book2, 15 in, 1TB SSD, 16GB Ram - I am pleased with both machines. I am the Lead IT Tech for a company here in Germany and they are on the brink of spending a boatload of money on the SB2 15 Inch by investing in 12 of them. They are all around great machines and minus a small snaffu with my SP4 - which Microsoft promptly, (with a little bit of teeth pulling on their end) - I got a refurbished machine within 2 weeks. I was only without my machine for 1.5 Days total - Overall - great machines. I cannot stand anything the ever so proprietary Apple people put out. It's their way, or the highway - Not what I am looking for in a machine as I want to be able to do whatever it is I want, without having to first "jailbreak / void warranty" a machine. Anyhow, for me - its BOO on the Apples.
