Let me begin by saying~ I love love my surface! Coolest gadget I have ever owned. There I was at the best buy helping my mother shop for a new laptop- and bam this beauty caught my eye and I was the proud owner of what my mom respectfully calls a "lablet". Anyways, I digress. One issue that's plaguing me: when using the surface and trying to charge it- the charger often falls out with the slightest movement. I'm just wondering if this is normal or I should pop back to da best buy?
