Now that I have Tiger and am messing around with it on a regular basis on an old dumpy G3 iMac my Dad loaned me (it works surprisingly well, actually), I am quite happy with the additional features (automator, what a brilliant idea!) and apps (free iLife 08 for example) that Tiger has over the ones that XP..err, doesn't. To me, I am happy that I have the apps I need to allow me to do a bit more in less time than I was doing in XP, let alone the whole Leopard/Tiger comparison.
In my position, I will be happy to upgrade to Leopard eventually, but when it does, hopefully I will have had enough time to get used to OSX and all its little quirks. Sure, Bootcamp non-beta and Time Machine will be great features, but for now, I am happy to get to know Tiger that bit better before I upgrade. After all, I'm sure I can afford the £70 upgrade - it'll probably be worth having anyway and certainly cheaper than other* offerings.
*You know who I'm talking about. Grrr Vista...
Unfair analysis and comparison. First of all, iLife '08 comes pre-bundled with new Macs since (August 7, 2007) or a $79 dollar retail price. You are using an iMac G3 which probably came out in 1999, which probably came with OS 8.6 or OS 9.1 (iLife '08 requires a G4 processor). In this case you had to upgrade at a cost. iLife is not a part of Tiger. Applications similar to iLife are either free downloads for XP and or come with Windows Vista. They may not be the same quality as iLife, but they are available to the user on Windows with the OS or as a download.
I don't have a problem with comparisons, but make them true and fair. Right now, its Vista vs. Tiger, simply because those are the latest from both Company's. Similar to when Apple was promoting Tiger vs. XP because those were the latest on the market when making comparisons. I have read a lot of hypocrisy in this thread. When Microsoft delayed Vista, you made fun of Microsoft from dawn till dust. When its the other way around, its sacred and right. Apple is not immune to software development issues. The only "only" feature Microsoft dropped from Vista was WinFS, everything else that was promised, came with the RTM. Vista's issues are not related to buggy software either, its device driver support thats the problem and in most cases its the 64-bit version, not the 32-bit version which comes with all OEM machines and in the retail versions of Vista. The only thing I see missing in Vista, is an automation tool, but, its likely with so much third party support for the platform, you should be able to find one anyway.
I don't want to be a party pooper either, but, OS X upgrades over the years cost just as much or even more than Vista today:
OS 10.0 - $129
OS 10.1 - $29
OS 10.2 - $129
OS 10.3 - $129
OS 10.4 - $129
OS 10.5 - $129
Total: $674
For the majority of Windows users, when they buy a new release of Windows through retail, its usually the upgrade version:
XP Home $99
XP Professional $199
Vista Home Premium $220
Vista Business $250
Still cheaper than OS X upgrades over the years.
Other factors include that XP was ready at RTM, OS 10.0 was not ready at GM and both were released in 2001. Consumers see XP as good enough even today that Microsoft had to create more activation keys for it. It took OS X until Panther to reach good enough state. Also, Academic upgrade pricing does not count, since thats only a segement of the market. If do want to count it in, I will do the same with Vista which usually cost $40 when purchased through the University.
