My first Mac was a IIsi, was with a 13" color monitor, a whopping (upgraded!) 5 MB of RAM and a HUGE 40 MB hard drive. With the Laserwriter, the keyboard ($160 extra!!!!!) and mouse, it came to a whopping $4240.00 on Oct 10, 1991, and that's WITH the faculty discount from the Oregon State University bookstore. Mind-boggling, isn't it? (I've kept the bill - it's pretty funny, these days!)
The computer itself, without the monitor, was $3420. That was the most we ever spent on a single Mac, with the exception of a Powerbook 3400 that my husband bought with a grant, but later returned to the university. The Lombard Powerbook was about the same, but everything since then has been cheaper, unless you count some of the upgrading I've done over the years, that is!! The IIsi is long gone, but we still have the Lombard from '99...it runs iTunes in my husband's workshop.
