The iPad mini has all the specifications we already knew. It has a 7.9" display, with a rather paltry 1024x768 display. Because iOS doesn't support different resolutions very well, Apple had no choice but to sit at the bottom of the barrel here - bested by just about the entire competition. Still, resolution isn't everything, and considering how Apple has been putting out some excellent displays as of late, I'm very curious to see if it's any good in real life.
Inside, it comes with 16, 32, or 64GB, a dual-core A5 chip, and all the usual connection and wireless options. It, of course, packs the new Lightning connector. The true beauty, though, in my view, is the enclosure - proper aluminium and glass. No plastic crap that we see on so many other tablets (including my beloved Nexus 7), and yet still very light and thin. I'll have to properly hold it, of course, but I can make an educated guess and state it'll feel better in the hand than just about any other tablet out there.
As for price, the base model comes in at $329 or €329 - which is considerably more than the competition, which has better hardware, worse enclosures, and a different, better/worse operating system (take your pick). What is undeniably a huge advantage of the iPad, though, is application support, as Apple rightfully pointed out during the presentation. Android has lots of catching up to do there.
Apple also updated the regular iPad, giving it a faster processor and better graphics chip. This may have something to do with the Retina display requiring more power. The iMac has been updated as well, with a thinner enclosure (but an ugly bulge) and improved specifications. The Mac mini has seen a specification bump, and the MacBook Pro 13.3" has gotten the Retina treatment.
Overall, lots of cool new stuff - but still no updated Mac Pro. What's up with that thing? It's like they keep it on life support just to torture it some more. Kill it, or update it, Apple.
