I've been having issues with my MBA, so last night did a full erase and re-install. Something I've done a couple of times a year ever since I've owned Macs. But its dawned on me that, unlike before 10.7 when OS X, iLife and all my apps came on disks, now its all online giving Apple the opportunity to force us to upgrade. In a year or two, I guess I'll no longer be able to clean install this MBA (doing so and then trying to download, say, iPhoto would throw-up "This version is not compatible with your Mac" forcing me to buy a new Mac!). I panicked last night when I realised I couldn't get hold of iWeb at all. Thankfully I copied it onto a USB stick from a friends Mac. It worries me though that Apple can now artificially end-of-like their products and literally force people to dump them.
