Im not starting a war here, im just asking opinions, so please, if your not here to make a point and jusitfy it, dont post. I have both OSX, vista and xp on various laptops ( vista and OSX both on my MBP). I admit there are updates to vista every 5-7 days. they usually are not that big though. when i update the OSX installation though , although the updates are less frequent, they are huge! currently the software updater lists 8 updates for the Mac and the total size is not far off 700 mb in size! in fact, ive noticed all mac updates are quite big( taking into account quicktime updates, itunes updates etc) compared to the size of the vista updates. it got so bad, that i had 60gb of space for OSX, and with only the standard apps that come with apple, and my own installed office mac and photoshop elements, i only had 5gb left out of 60 gb partition. I ended up having to remove windows so as to be able to resize the OSX partition. When i dont store any files ( photos, vid, music etc) on the computer, 60gb should be more than enough for the OS and its apps, within reason. this turned out not to be the case with OSX. so, mac's campign of giving out about updates for windows taking the spotlight from their own update issues, where their updates are huge. has anyone else encountered this? what are your thoughts?
