- You forget, though, that at the low-end of a peecee, you aren't forced to
- buy the best of the best right off the bat. You can start out with a
- pretty cheesy system -- and then upgrade it, bit by bit. For starters,
- you can get a minitower case HERE for $33 US. It's a good case, too.
- Nothing flashy.

- However, at the end of a two year cycle, chances are that your
- motherboard is woefully inadequate and all but a few of your
- state-of-the-art add-ons are as well.
-
- It gets worse if you buy one of the less reputable "systems."

- Well, that's a valid point of debate IMO. Memory protection as *I*
- understand it is basically the OS maitaining the integrity of your
- overall memory pool by keeping programs from interfering with each other.
- Say, program X is loaded into memory at location Y, and program A is
- loaded into location B. Program X tries writing to program A's memory
- space -- program A crashes like a locomotive with wings. With properly
- implemented memory protection, the OS intercedes and tells you "Program X
- caused a memory integrity fault" or something along that line, then kills
- off program X and lets program A live.
-
- The problem is, this doesn't always work as advertised. You mention
- crashing peecees -- simply "crashing" isn't always caused by memory
- faults, ya know. However, I will observe that if Win actually HAS memory
- protection, it's pretty pitiful.
-
- Down side of memory protection: say goodbye to Amiga's efficient
- multitasking and resource sharing. Passing a message from one program to
- the other (ie, AREXX) would under the above model cause a SERIOUS
- violation of memory as program A created the message, what's program X
- doing READING it? Uh oh, shut it down!
-
- In other words, AmigaOS has to get its grubby little fingers involved.
- Yech.
-
- So, as I said, memory protection can be a boon, and it can be a bane.

- Peecee games might have operated in that resolution 5 years ago, but
- nowadays that's simply not true. Go to a well stocked software vendor
- and ask to see a demo of some of the newer games like Cyberia or Descent.
