i went to buy a 2G jump drive yesterday; the brand was memorex. in small print on the bottom of the package, it said that on macs, only usb 1.1 was supported. on the apple storefront, i read some bad reviews of the sandisk cruzer drives. some say they reformat when you use them with macs and pcs. anyway, what brand of jump drives do you guys use? ps-this is my first mac.
