Yes, Indigo is very good and very well supported. Thinking Home was very good, and may be again, but I have to question the level of support with only one (bug-fix) update since 2001.

My opinion of Indigo is that it has become bloated with capability that most average users are not very interested in and at around $200 for the current version, way to expensive. They again, this is the first upgrade of Thinking Home in literally many years. I used Thinking Home for many years, till it failed to work on my machines/OS. Right now I am using the previous version of Indigo, which was about half the current price and it is working fine for my needs on my Intel Mac's running Leopard. Frankly I am disappointed with all of the Mac based automation products, given their level of cost and/or timely updates. Hopefully the freeware Sourceforge project will eventually provide some needed competition and force the commercial vendors to either rethink their business model in terms of good support and value, or step aside for a hopefully a more customer oriented vendor. Given the pricing structure for home automation (other than X10) the products seem targeted only for the economically well heeled. The issue with X10 is that their operation can be inconsistent, and at times unreliable. Right now I regard Home Automation to still be in its infancy and needs to mature in order for it to migrate out of the hobbyist real and become practical for the general public. It seems right now that the only way to obtain a stable properly installed system, without being a tinkerer is to pay big bucks to have a specialist install and configure the system for you. The bottom line is that reliable equipment and software for the hobbyist is costly and somewhat fickle, and and to have it professionally done can become very expensive. I would expect it to remain such until competition and consumer demand results in more reliable, less expensive products that are easier to install, configure, maintain, and use.

First of all, might I might ask that if a 'contributor' going to assault another contributors character that the proper terminology be used - i.e., the use of the word "Spam" in your comment:

From Wikipedia:
Spamming is the abuse of electronic messaging systems to indiscriminately send unsolicited bulk messages. While the most widely recognized form of spam is e-mail spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, mobile phone messaging spam, Internet forum spam and junk fax transmissions.

Contrary to the opinion that was expressed in your comment, my message was not indiscriminate, and it was solicited, as was yours. Comments are part of the culture of MacUpdate, and have always been solicited so long as they contain civil language and do not involve personal attacks.

If you read my comment carefully, you should note that I cast no aspersions in regard to any individual, or group of individuals, directing my comments to characterize my observations of the Home Automation products that I am familiar with, and making constructive comments regarding the evolution of an up and coming public domain effort. My focus a purpose was to provide users with a summary of my experience with Home Automation Product and my overall opinion of them to assist them in making an informed decision without having to page through numerous windows or tabs, and multiple websites.

If MacUpdate offered a side by side comparison of similar products, in chart form, along with comments then your comments about viewing all the information about multiple products would be correct. However to the best of my knowledge MacUpdate does not provide this feature, at least to unpaid subscribers, and I have not seen it offered by their competitors. If you know different, I would appreciate hearing about it from you.

Perhaps you might consider offering this suggestion to the MacUpdate development team. I certainly cannot, since doing so would be stealing your idea, which would conflict with my basic core values.

Given that your comment took exception to my comments, and you certainly have a right to your comments and opinion, as do I, let me point out what I believe is fact in my previous and others comments:

FACT: I did not post the original comment about Indigo.

FACT: To the best of my knowledge Indigo, currently is the most expensive, stand alone PLC control software available for the Mac. If you know of a more expensive product, for the Mac I would be interested in hearing about it.

FACT: Many of the Home Automation Products contain features that less than 50% of the purchasers use. In order for this number to be greater than 50% evidence would need to be provided that over 50% of the users are scripters, or programmers and that would probably be extremely surprising to the industry as a whole.

FACT: A significant percentage of Home Automation Systems are installed by professionals. I invite you to provide evidence that a professional installation can be equal in cost to or even just slightly more expensive than a self-installed system.

FACT: X-10 systems have a history of anomalies. Just do a Google search on this subject. In particular, they are somewhat sensitive to electrical noise on the power line. Otherwise companies would not be selling filters and signal boosters to get rid of the noise or overcome it.

FACT: Indigo 1.8 was a good product at a fair price. However I do not believe it is currently available for purchase. It is what I am still using. My comments regarding a "bloated Indigo" referenced 2.0 not 1.8

FACT: A significant period of time has passed since Thinking Home has done a major update to their product. It was enough time for many, like myself to feel the product had been abandoned. Many, again like myself, having up-to-date computers and automation equipment, felt that the only alternative at the time was to switch to Indigo.

However given the direction and the current cost of Indigo, I am looking for an alternative. If Thinking Home had a history of addressing and responding to users needs in a timely manner, that choice might very well be Thinking Home. However this is precisely the issue that caused me to give up on it and switch.

A wise person, whose name escapes me at the moment, said regarding human behavior, that: "Past history is generally a good predictor of future events." My experience generally leads me to agree with this philosophy.

So given the history of Thinking Home, in relation to timely updates that address current OS releases and new Home Automation products, I will leave you with this final thought.

Why should users expect the future updates and support from Thinking Home to be different from their past history?

You mean "the developers' hobby rather than their vocation". An avocation is similar or the same as a hobby.
