Here is my situation. When I'm on vacation in Spain I usually go to some wifi hotspot and download my emails on my laptop. This year I want to be able to do this on my ipod touch. Then I go to my vacation home and would like to transfer the email attachments to my laptop. There is no internet connection at my vacation home. Using my MacBookPro's built in wireless card I can connect to my iPod Touch (still no internet, just laptop to device). After transferring the attachment files (mostly jpegs, zip files and word docs) to my MacBookPro, I work on them (I'm a graphic designer). Then I want to transfer the result of my work (usually as PDFs) to my iPodTouch (still no internet, just laptop to device). Then I would go to the wifi hotspot and send these new PDFs to my clients over email. I'm not interested in reading or doing anything with these attachments on my iPod, I just want to have a possibility of storing the attachments and bringing them "home" to my laptop and vice versa. I was about to get "ReaddleDocs" today when I stumbled across thread about "PDF Expert". It seems that PDF Expert does the same, but is better/newer in functionality? Will PDF Expert (or any other app) enable me to do what I described above? Saving attachments (not just PDFs, but also zips and docs) to my IpodTouch and being able to send files I store on the iPod via PDF Expert as email attachments? My main incentive is that when I'm in Spain on a hot summer day I don't want to log my 17 Mac Book Pro around just to send and receive email attachments. Thanks for any advice!
