If the price wasn’t too much of a giveaway, the meager one hour it took to install this ‘upgrade’ to leopard was. Everything from the name to the official wallpaper shows that that’s exactly what it is. An upgrade. It won’t go head to head with Windows 7. It doesn’t need to, it’s already streets ahead.On the face of things, I can’t see any noticable improvements with the user interface. Nothing sparkles the way it did when upgrading from Tiger to Leopard. Yes, exposé is a bit more organised and you can now scroll in stacks but these minor improvements pose the question ‘why wasn’t it like that before?’ There is the new QuickTime player (but I use VLC) and there’s support for Microsoft exchange (but I use gmail). So these changes simply don’t affect me. The greatest difference was the space it freed up. Leopard left me with 19GB on my hard drive, Snow Leopard gave me back 12GB extra space! Pretty amazing when my other laptop Asus eeepc with XP has no room on the partioned C drive for any software because it’s full to the brim with the operating system and common files!So in conclusion, Snow Leopard doesn’t give that wow factor received succeeding the installation of Leopard but for £25 and an early release, what did you expect? What will the next big cat be? That’s the one we want to look forward to!
