Seems people engrossed in Windows and never really used a Mac aren't understanding what one can do. Mac to Mac with one as an external drive requires a Firewire (IEEE 1394) connection (at least I never tried USB); not very well supported in Windows. This is commonly used when one buys a new Mac and wants to transfer files and installed software from the old Mac to the new one. I have done it from our iMac SE to my PowerMac. When I used Windows and needed to up grade I would use Alohabob's PC Relocator; which came with a USB network cable. Unfortunately MS bought PC Relocator and buried it. After installing SP2 to XP the version I had (v3.x) no longer works. MS is offering no upgrade unless you buy Vista or 7, even then it is unreliable. Tried Vista, got sick, won't even look at 7. So I bought the PowerMac and dumped Windows as my development platform.
However, Apple does not have a tablet PC and the after-market ModBook is gawd awful expensive so I bought a Toshiba Portege M200 Tablet PC with a multi-base running XP Tablet Ed. Nice enough for the $250 I spent. Old style Graphics tablets and my aging eye-hand abilities make it necessary that I use a drawable screen/tablet for PhotoShop, Manga Studio, and Anime Studio. A Wacom screened graphics tablets start outside of my present budget at around $1000. I don't think so.
I am here now because I would like to try and do the external drive thing with my M200. I.E. work away from my desk, get back to my office, and plug it in as an external drive. Yes, you can do this Mac to Mac (OS X/Unix). Having to man two computers and get into my network is more than I want to be bothered with for this task. And, considering I was able to do this 30 years ago with AT&T Unix SVR32 makes it a bit aggravating.
So, anyone come up with a real solution?
