Bottom feeding, a little derogatory for those who either can't afford or want a mac or have more sense than money and recognise a good deal when it comes along at 220-300.
No matter how you want to dress it up the Mac's market share is small and these figures don't represent true market share, just an artificial benchmark. Lies, Dam Lies and Statistics 
Worldwide Total market Share is somewhere between 5-7%
US Market share falls somewhere around 8-10% (US Marketshare is always higher for Apple for some reason, even in the iPod/iPhone world)
So yes depending on who you believe (every publication has slightly different numbers) it is a small piece of the market. But the important thing is its growing at a steady pace, Apple always compares its year-over-year growth to the rest of the PC Market at every earnings report, If Apple's quarterly reports can be trusted. (Lies, Dam Lies and Statistics

Im sure they are fudged at least a little)
Mac,
I paid $800 for my Dell Vostro 17" Laptop
2 gig of Ram and 160 gig Hard drive.
I don't consider it a bottom feeder..... :'(

No thats certainly not a bottom feeder, what I am referring to when I say "bottom feeders" are these Wal-Mart / Costco / Best Buy / Etc $299 special Machines witch some 2 year old Celeron/Sempron processor, 512MB of RAM and trying to run Vista machines.
Because it never ceases to amaze/irritate me when a person Walks in the store and Looks at the Mac Mini and says "$599 for this and no Monitor?" People just don't understand the difference in the quality of the parts between a $299 machine and a Mac Mini or a Dell Vostro such as yours.
