I want a tablet. I think that they are unbelievably cool. But, at the same time, I can't bring myself to buy a big cell phone. I already have one of those, and its screen is over 4". That IS a tablet. Cell phones are also a fantastic toy, because like a computer, it is a toy with legitimate uses beyond being simply a toy. It's very easy to rationalize the purchase of a bad-ass cell phone. It is not similarly easy to rationalize the purchase of what amounts to a more-bigger cell phone.
But Windows 8 makes this prospect different. The boot time on Win8 appears to be nearing the instant-on nature of current tablets, although will likely never actually get there, and having a tablet mode or something similar would allow Win8 to extend the battery life to something beyond the few hours possible on most super-lite laptops. Moreover, since the OS is the same, I will be able to do actual work on a Win8 tablet.
It also prevents ridiculous artificial restrictions on tablets. For example, various tablets try to market themselves as nearly-computers, but most of the media websites that would be best-suited to the tablets: Hulu, Spotify, etc.; are blocked by the media companies. It turns tablets for the majority of people into glorified e-readers.
Granted, I think many of the problems with tablets has to do with the app development. There's very little heavy-hitting software available for cell phones or tablets, and I'm perpetually puzzled as to why. Android and iOS are HUGE markets. There should be tons of things for power-users, yet the bulk of the market is dominated by super-small little developers. Is it raging arrogance on the part of the big companies? Is it something about the phone/tablet market? What?!
Regardless, Win8 eliminate all of these issues, at least for me. I'm not saying that I would ever get a tablet. I might opt for a super-thin laptop. But at least this makes what is arguably one of the coolest things to be perfected, like, ever, a reasonable option.
