Just read some interesting stuff in the latest "MacMall" catalog which doesn't make sense to my meager mind. Is the 601/120 processor in the 7200/120 line faster than the 7500/100's processor? If so, is the 7200/120 faster than the 7500/100? The only reason to buy the 7500 in that case is to get the video input capabilities. Then how much does that card (or a in/out video card) sell for separately? In the MacMall ad they are pricing their 7200/120 8 MB for $1899, while their 7200/120 16MB is going for $2299 = a $400 increase. On the same page you can upgrade the 8MB model by 8 more MB for an additional $359. Go figure!! They list no other differences in the 2 systems...
By the way, if you're thinking of ordering anything from MacMall (aka Creative Computers) they use Federal Express's Logistic Services Management to distribute their products. So what, you ask? This is what: this gives them a legal presence in the State of Tennessee, so they are obliged to charge Tennesseans state sales tax! This would add $204 to $248 on the above models...
