You're laughing at your own joke then because I didn't say ANY Windows tablet outselling iPads but ALL Windows 8/RT tablets, hybrids and convertibles combined, which excludes conventional clamshell touchscreen laptops.
I can see this happening. I came back for my masters earlier this summer and I saw a weird trend. Increasing amounts of Surface Pro and Surface RT tablets, I thought I wouldnt see any really but they keep increasing, a lot of my friends are getting one, classmates I meet want one. I could definitely see the combination beating out a single iPad generation. I myself have bought 2 W8 tablets and neither are cheaper than the most expensive iPads. I do have an iPad myself but its the first gen and I will never buy another because its more of a toy than anything.
