Acrobat, Autoroute, Norton (Ghost+NIS), "Office Ready"
I still use Acrobat 5, I may look at Foxit. Occasionally Acrobat 5 is apparently required to say "this document may contain features newer than your reader can support" but so far I have never found a single document that wasn't usable.
Microsoft bought UK outfit Nextbase for their Autoroute package. Within a couple of versions, they'd completely broken it. Autoroute 97 was so bad that one of the mainstream UK PC rags was seriously suggesting it be taken off the market (has any serious rag been so brave yet with Vista, which seems to have similar issues?). The "97" also illustrates that software rot is not a recent phenomenon. Fortunately the bottom's fallen out of the Autoroute market in the last year or two; who wants to pay for Autoroute when for a little more money you can buy a complete satnav.
Marginally more recently than Autorute 97, maybe five or so years ago, Symantec managed to seriously break both Norton Internet Security *and* Norton Ghost. No more Symantec here or on any PCs I support, which is kind of hard because Symantec are one of the leaders in factory-installed consumer/SME blackmailware aka trial versions which can't readily be uninstalled by punters AND cost punters money once the trial is over.
Which leads us neatly to MS "Office Ready", the current rash of PCs factory installed with a two month "free" trial of MS Office 2007, which has to be done because there's no other motivation whatsoever for either Joe Public or the sensible helpful IT (s h IT, geddit?) Department to look at Office 2007 rather than any previous Office (or even, heaven forbid, OpenOffice). Then after two months pay another £100 or more to the PC supplier to "activate" Office (what, no edu discount any more?). Way to go, Billco, you finally caught on to the Symantec scam, only took you a few years!
The UK has laws against inertia selling, why is nobody testing them on this kind of thing?
Merry Christmas everyone (well, except the tosspots that bring us this kind of thing, you can burn in hell forever please, and never mind 'goodwill to all men').
