This is the best phone I've owned. I moved over to BlackBerry in 2008 and haven't looked back and by far and away, this is the slickest, fastest and most fun to use phone yet.
I use many websites for streaming media, and is only made possible with iPhone and Android by means of downloading an app. Something you are forced to do in order to use a product, but with the Z30 they work straight from the website. Which is a huge added bonus. All the apps that I would download were already preinstalled, so happy days!
BlackBerry Maps has been given an improvement in BlackBerry 10 and now gives turn by turn voice instructions and current traffic conditions, something that is very helpful.
The Hub is an excellent idea and I like the way you can leave the Hub open in one notification (email/Facebook/Twitter) as opposed to seeing all together.
The sound quality is excellent, both from its internal speaker and through headphones. Having NFC (Near Field Communication) technology built into the phone is a lovely addition. I believe BlackBerry started putting NFC on the Bold 9900 prior to the Z10, so to keep it in was an added bonus.
Unlike an iPhone when you plug your Z30 into your computer, you don't have to use something like iTunes to transfer files to and from the device. Yes there is BlackBerry Link to back your phone up with but the fact your computer picks the Z30 up as a USB drive means you can drag and drop files straight in.
Contrary to what people have been complaining about this phone with their ill informed comments, I think it is a superb piece of kit, it feels good to hold, and maintained properly, the battery will last a long time between charges.
