An anonymous reader writes "Ars has an extensive review of the newly-released BlackBerry 10 operating system. Since it's such a late entry into the market, the tech community has been eyeballing the new operating system with trepidation — would all that time go to waste with a poor offering, or would BlackBerry 10 be a reasonable alternative to iOS and Android? Well, it seems BlackBerry (the company formerly known as RIM) actually put the time to good use. The review finds most of the UI innovations to actually be.. innovative. "BlackBerry took a lot of time to see what the competition is doing, and then it worked to refine its operating system. It essentially had an excellent cheat sheet, filled with everything that has worked wonderfully and all the things that have bombed. That said, BlackBerry still has to mold its product for its two huge core audiences: the business-oriented multi-tasker and the developing smartphone markets. To that end, it has included all of the essential features and apps to appeal to both of those parties. The corporate user has his or her share of content to watch on the train ride to work, games and apps to help keep busy when not entrenched in a meeting, and the perfect Hub for messaging (not to mention the literal split between work and personal environments)." However, the review also notes that the system is not really designed to make people drop their Android or iOS devices, so uptake is going to be slow at best. The question for the platform's success (and the company's) is no longer 'Is it any good? but 'Is it too late?'" There's also a review of the z10 smartphone itself.
