I am carrying my Samsung mini S1 250 GB with me as a mobile file cabinet all the time at work.  The external HDD is formatted to MS-DOS (FAT 32).  The files are in MS Office files: Word, Excel, Access, PowerPoint; pdf, jpg, flv, zip, etc.  I would like to buy a Pogoplug Pro connected with my external HDD in my office.  I am unsure if Pogoplug is a right device to do the job for me when I use iPad 2 or iPhone 4 to access all the files in the external HDD like a networked drive.  What is the UI to access the files, similar to Windows Explorer or Finder?  I appreciate any user experience sharing.  Thanks!
