Mmm. I agree with the many posts noting that since the Windows OS moved from 98 to the NT set-up (2000 and XP), Win. has gotten better in ways. You can leave it on now for days without the needed re-boot ever 24 hrs. or so. It - in theory - now isolates programs so an isolated crash in a certain program doesn't mean a crash everywhere (in theory).
I think windows is okay, but it's not as "fun" as the Mac OS. Although I do agree with the recent article in Macworld that Apples free software does do some odd things - the example given in the article was the block on Apple's software to keep folks from copying sceens of of DVDs, a block not required by law or present on windows machines.
But the real thing is hardware. PC Magazine recently noted that there were only two computer companies making a full line - econ. through living-room size monsters: Dell and HP. Now, in certain areas - I really like what Apple has done - it's powerbooks are a great value - just try and price out an IBM T30 thinkpad coming close to the the 15" - and no superdrive option, no option for anything more than 16 megs of video ram, etc. As I've posted elsewhere ("processor upgrades" - under the hardward discussion) the current Apple offerings keep pace with the consumer intel offerings - and exceed them.
When you get to the workstation - things start to fall apart. Apple's Power Macs are intended to satisfy a number of folks - but I'm not sure that two lines wouldn't be better there. (A higher end offering the big brother of the IBM 970 perhaps or at least taking advantage of IBMs highend processor R&D?)
For example as of this morning for $2400, one could get a Dell Precision Workstation 650 with: 1 Gig of Ram (double your ram free promotion makes that possible), a 64 Meg - and here's the kicker 8 X AGP video slot(as opposed to the powermac's 4X), a dvd-r drive, 1394, USB 2, a XEON 2.4 GHz processor (my feelings are that the p4s really don't dominate over the g4 given the benchmarks out there [See first looks in this month's PC Magazine for a photoshop comparison, for example), an 80 gig HD, with MS XP Pro and MS Office. For the Price of a $3200 power mac - I could bump up the Xeon to 2.6 and add a second 2.6 Xenon - yes two 2.6 GHz Xeons, 1 Gig of Ram, an 8X AGP slot (only a 4X card unless you add more money) with 64 MB or ram for $3200. At that point - there isn't an offering from apple that is so powerful from a hardware standpoint.
[update: I now think my last sentence above is perhaps not the case. I looked at some benchmarks (see the PC Mag Feb. 4 bench mark of the P4 3.08 vs. the Xeon 2.8 in CPU roadmap article and then compared with the text benchmark in the first look of the 1.25 dual G4 in PC Mags first looks) and it appears that the G4 will do well against the Xeon at 2.8 - but that is using only one Xeon. This - happily - reduces my impression that PC midlevel workstations were really gaining on the dual G4s re: price - although I have no benchmark for a DUAL 2.4 system that I priced out to $3200 (a dual 2.8 system would be much more) against a dual 1.25 G4 system - there may be very little difference if the XP or 3rd pty software isn't really taking advantage of the two chips - and if that's the case, the 1.25 G4 is going to be the faster offering if it can hold its own and exceed a p4 3.08 GHz in photoshop... arg! my quest to determine the obvious better value for power is foiled again. The only real thing I can say for the Dell now is that if you have another few thousand above $3200, you can add the two 2.8 Xeons, add the 256 MB 8x vid card ($1400 by itself, I think), SCSI Drives in addition to the ATA 100 drives, etc. - so, the obvious advantage is simply expandability but one quickly goes into a different class of computer not made by Apple when taking that road...].
Now - of course, I mostly write things on my computer - do I need that kind of power - no. But if I have $3200 burning a hole in my pocket, I can certainly get that kind of power - plus If I did have a need I could upgrade the same box - higher speed dual processors, an 8x card with 256 Megs of Video Ram, etc.
When the software isn't that bad, it's this kind of hardware flexability and access to workstation processors and graphics cards that may make folks actually develop a liking for XP, even if its not as fun, or pleasant, or easy.
