Walt Mossberg at AllThingsD has a review of 3 convertible Windows 8 tablets which is succinct, but makes a subtle point (if you read between the lines): a convertible laptop/tablet is a compromise. None of the devices he reviewed are particularly light or thing. None of them have battery life that approaches the iPad or mainstream Android tablets. And, as we’ve seen from past reviews, Windows 8 doesn’t seem to be a great tablet OS, and the presence of tablet features may have compromised the traditional PC experience. But these convertible tablets beg a bigger question: will consumers change their mind on these things?
