http://www.macworld.com/weblogs/mac911/ "Hardware: What computer are you using and what capabilities does it have? On one end of the spectrum, let¹s say that you¹re running OS 9 on a 400MHz Blue and White Power Mac G3. Even though your computer meets Tiger¹s system requirements (PowerPC G3, G4, or G5; built-in FireWire, 256MB or RAM, and 3GB of hard drive space), Tiger is going to run like a pig on your Mac. Megahertz matter in this regard. If your computer doesn¹t offer a processor that runs at 700MHz or faster and you¹re running Mac OS 9, I¹d forego the upgrade. Putting a Tiger in your tank isn¹t going to help until you get a much faster Mac." I've now installed Tiger on a G4/400 desktop, a G3/400 Powerbook and a G4/667 TiBook. The wife is in no hurry to have me install it on her FP iMac/800 and for my G5s and other G4s, I haven't yet found a compelling reason to make the update. Spotlight and Dashboard are major league yawns, to me. I've got a dedicated fax machine, and some of the other improvements, i.e. Safari's RSS, nanny warning, slow trashing, et al., are as useful to me as a banana is to a fish. The most dramatic speed bump I've noted are boot times, which I suppose are nothing to sneeze at when we're dealing with a lot of updates that require rebooting, but that's just not going to cut the mustard here. In conclusion, although MacWorld's summary may be a bit too heavy on the rhetoric, the authors comments do largely dovetail with the experience I've had updating the aforementioned hardware. As always, YMMV, and some settling of contents may have occurred during posting. -- -John Steinberg email: P.S. I was kidding about the Jobs thing ... or was I? -= I link therefore I'm spammed =-
