Hello, I'm a first time poster here and a college student that's considering getting the Surface Pro 2 as my first Windows 8 tablet/laptop/desktop but I do have some reservation I hope experienced users can answer. The first is running music or video metro apps in the background while I'm using the desktop. The second is continuing to running programs and downloading/uploading data with only the screen off to save power while at school. The third is using Bluetooth headphones which I've read have problems such as audio lag, losing connection, etc. And using 2 Bluetooth devices at the same with such with a mouse? Other problems I see people are having includes WiFi, corner screen input/bleeding/flickering, audio, Windows scaling. The Microsoft Complete Extended Service insurance is also something I am a bit unclear what it entails from their website. Such as additional limited warranty coverage, accidental warranty coverage, deductible, accessories. The first web page states additional 1 year of limited warranty coverage then this page states up to 3 years of warranty so are there multiple Complete Warranty packages? And how much do they cost?
