re: Microsoft's Next Surface Pro: Comeback Kid?
Forrester data shows a fairly even split between people who want laptop-like tablets, people who want tablets that use keyboard docks, and people who want tablets that have nothing to do with physical keyboards. To me, that's a sign that the use cases, form factors and technology are still in flux, with a lot of people caught between features that sounds good in theory and features that actually work well in practice. This would explain why the first round of Windows 8 tablets struggled-- lots of functionality, sure, but also lots of compromise. As Bob124 aptly said, a house boat is neither a great house nor a great boat.
Then again, it's also possible that use cases around tablets are fragmenting. The tablet form factor might become ubiquitous, but all the variations (detachables, hybrids, bigger screens, smaller screens, etc.) might be confined to niche pockets of the market. This scenario would at least allow Windows 8 to become widely used across a wide variety of devices (a la Android), but it wouldn't help any single OEM to produce a world-conquering device (like an iPad).
But it looks likely that Microsoft will have a new Surface to show us in just a few weeks, so we'll see what they come up with.
