Re: If you can't own the market..
This .... this ... this is a fairly reasonable post from Eadon. What strange new world can this presage?
I don't agree with much of it, mind you; Windows is an entrenched technology, and like all such, it will be around for a long, long time (in IT terms). How many shops are still running, say, IMS? A whole damn lot of them. Hell, a few times a year I see queries about potential customers who are running even more obscure mainframe DBMSs and other software. There's a reason why CA can keep milking the maintenance revenues for products like IDMS.
As Tim Worstall pointed out re Dell the other day, there's no reason why a company should last forever. Someday the remains of Microsoft will likely be acquired by something like CA, to scrape up those final years of maintenance revenues. But it won't "sink like a stone", because the vast majority of existing Microsoft business customers have no reason to take the huge costs of replacing all their existing Windows-based software, or of retraining their staff.
Once an OS is established, it only disappears through a long, slow process of attrition.
 We'll forgive the misspelling of "wither" - this time.
 To be fair, CA has added a number of features to IDMS over the last twenty years. But that's been commercially justifiable because it keeps the existing installed base happy, and they keep paying high-margin maintenance fees.
