TopTechTips posts a story about "a new piece of Apple software/hardware called 'Pal'". TopTechTips claims they were sent screenshots as well as a box shot, which remains on the site.
- Update: It is looking more and more like this piece of software or hardware from Apple will basically take your desktop/files and put it on to "Pal" (Assuming it is a Firewire drive or more likely an internet service) and you will be able to access your desktop and all of your preferences from any Panther Mac that has "Pal" installed.
The box shot mentions Mac OS X 10.3 being a requirement.
ed. note: Still trying to gather details... while some are speculating it may be hardware, the description appears to be of an Internet/.Mac service.
Update: As best can be gathered... despite claims that "various other websites have been sent them but Apple's Legal team has asked for them to be removed" -- this appears to be untrue.
The photos did appeared briefly on Spymac.com earlier today, but were removed by the poster, and not at the request of Apple Legal.
Some point to "Coming Soon" features at .Mac describing "Access Anywhere" as possible evidence... however, this teaser has been posted for weeks and is as likely to represent the inspiration for this rumor.
