No overheating/runaway fan, no yellow lines or light bleeding, no WiFi slowdowns or connectivity issues, no problems resuming from standby, no crashes or lockups. Every single issue I've read about here my device does not have it. Batch 1435, impulse purchase from Microsoft kiosk at the mall (went there to get cologne, ended up with surface) a couple of weeks ago. Battery life is at least 7 hours daily with normal to intensive use - web browsing, emails, Netflix, vpn connected into my office at times, Lightroom and Photoshop photo editing, etc. Watch me jinx it, might start with issues any moment now As context, I use a mac pro and a MacBook pro at home, and an iMac at the office. This is my first encounter with Windows 8 that I can tolerate. As much as I think it's atrocious on a desktop, it's outstanding on the surface, I much prefer it over an iPad. The sp3 is exceeding my expectations in every single way.
