i'm searching around for a PDA which could sync well with mac OS 10.5.5, but i'm not sure which one to go for. I'm looking for an inexpensive handheld device which can allow me to view microsoft word, excel, and other pdf files like ebooks. I like the iPhone concept a lot but it is just not suitable for heavy users of microsoft office and pdf like myself. Therefore, i need some advices on choosing a PDA/handheld/palm for mac running microsoft office 2008. Please tell me more about syncing issues, any issues with compatibility etc. Please help! thanks!!
