Well I own a Macintosh G3 with 512 MB RAM and all the bells & whistles I might want.
The greatest frustration I have encountered is the sometimes slow release of Macintosh
versions of common apps.

As a scientist I use my Mac for graphics applications and just about everything
else, including business & programming. I also have a number of storage options
floppy, ZIP, JAZ (Re:iMacs & lack of floppy drive-please note that I foolishly insisted
on buying an external floppy and it is gathering dust-most file transfer requirements
exceed the low storage capacity of floppies-think external ZIP or JAZ drives instead-I have both).
But I digress .... I have been using Macs, PCs & UNIX etc..
machines for 15+ years and have continued to select Macintosh computers as my
computer of choice for personal & business use.

I would consider an iMac an entry-level Macintosh and not representative of the
higher end Macs, therefore please don't rush to judgement on the stability/utility of
Apple computers. Apple technology is always on the cutting edge and their
hardware design group has provoked a revolution in the whole PC design industry
- what I call the "beyond beige" era. Think different!
