Apple As widely anticipated, Apple's new major OSX release is available this morning, download-only, for $29.99 USD in the Mac App Store. There's a quick copy and paste job of the feature list after the jump. Also as expected, there's a new, Sandy Bridge-based Macbook Air. Update: A reader pointed out John Siracusa's Lion review at Ars.

Shrinks a partition

Mac OS X still can't "dist-upgrade". Instead, the "installer" shrinks your existing partition, puts itself into a new partition, reboots your Mac from the new partition and installs Lion.

Sounds fine, until you realise that resizing partitions only has a 99% success rate. Statistically speaking, one in every hundred Lion upgraders is going to lose all their data.

A good way of selling Time Machine units?

I dunno - it never caused me any great problems when I used it a while back. However, there's danger in any partition resize and everyone should have good backups anyway, especially for mobile devices!!

Time Capsule. I got a 2TB a short while ago after looking for a replacement wireless router/NAS (pure NAS, not one with extra "apps") and coming to the conclusion that what Apple was selling was fairly close in price to the competition. Simple install all in one box won.

Actually, the installer blesses a new boot bundle on the same partition, reboots from that and then starts creating the Recovery partition as part of the install process from what I've read.

Other than that, there's nothing whatsoever important about "dist-upgrade". It's just a buzzword. The end result is the same. Though, Ubuntu still won't let users install the latest and great versions of their favorite apps without upgrading their entire OS. So, I can see why some would place importance on something like dist-upgrade.

Resizing partitions has been a no-brainer on Macs for quite a few years (since at least 2006 with the advent of BootCamp). I've not heard of any memorable catastrophes but I'm sure they've happened on very rare occasions. I'm sure dist-upgrades fail more often than partition resizing on Macs. However, everyone should have a current back-up before trying anything remotely major such as this, right?
