I know macs are cheaper than pcs when all costs are included (downtime, depreciation, etc) but I'm curious about comparative cost of owning mini ($800), iMac ($1200), mb($1200) and mbp($1800) over 3 year period (purchase and resale, intangibles aside). I'm certain mini and imac much lower (especially since applecare probably not needed), but how do they compare? How much more per year for a mbp over a mb? Has anyone seen this info anywhere? How did it look for the last generation of macs (ibooks, powerbooks, minis and G5s)? Thoughts, no flames please.
