Apple Mac OS X 10.6 Snow Leopard - MC223Z/A

+ the p.c. runs faster

- best part of 2 hours to install [worth it]

+ Loads faster, shuts down faster, some nice tweaks to already excellent existing features, advanced features may take some finding - if you've use OS X before you'll know what I mean :)

- None.

+ Smaller foot print.

- Trouble in installing on Macbook Air as it does not recognise remote disk on network having WEP security.

+ Easy to install - value for money

- Reviewer left no comment

+ Somewhat faster on the same hardware. Not a lot of change for the user, so no big learning curve like the poor users who are going to move Windows XP to Windows 7.

- Some device (especially cameras) don't work anymore in Snow Leopard when they worked fine in Leopard.
There are a number of bugs in the product, and it feels like it was rushed out too soon to try and beat Windows 7, but it's worth the price.

+ very easy installation without any problem, few nice tweaks, looks a little bit faster then before

- some software incompatibility (flash sc4 crashing more often then before) few other programs not working proper (ffmpegx)

+ Very easy and quick to install with no impact on any data. Overall price fantastic.

- Still some more things I would like on my mac but minor issues overall

+ Easy set-up, great price,

- Nothing overly SPECIAL, does improve on previous OS a fair bit, but its not a revolution in itself.

+ secure and easy

+ Lots of improvements. Everything makes sense - Apple's intuitive design shows again.

- Nothing I've noticed. Just the usual getting used to slightly different ways of doing things.
