The problem with Hype.
This is a major under-bonnet upgrade. It's like putting a V8 into a shell for a 4 cylinder engine.
I am using 2 MacBooks. A white 2.1 and a new MacBook pro 13 inch. I put Snow Leopard onto the White one to take a look at it. From a user point of view the benefit is subtle, the problem is, with an earlier than previously thought release (presumably to get ahead of Windows 7), it seems to have left some third-party developers off guard. For example Mac Speech dictate, have been concentrating this summer on major new releases (legal, medical). I think they thought I had more time to sort out the 64 bit architecture. A couple of applications I've looked at that haven't been tweaked to 64-bit, gobble memory.
These memory leaks, seem to me to be the primary problem, I think once 64-bit compliance is achieved their most of the problems being talked about will disappear.
A good friend of mine, an IT consultant, with over 20 years experience in this industry, and original Apple Mac fan boy, said to me last week "I think I'll wait for the dust to settle before I upgrade to Snow Leopard", thus a voice of experience! In a way, Apple have made themselves a bit of a victim here. Too much pre-snow leopard
hype and bringing release date forward. Apple have created problems for themselves, by giving red-faces to hey 3rd party developers, although I think in reality the are the problems are small and will quickly be resolved.
For the moment, I'm keeping snow leopard off my MacBook Pro, as speech recognition is a primary requirement for me. Once Mac Speech dictate have sorted out the 64-bit compliance, then I will upgrade.
