Im thinking of buying a Palm but Im having trouble finding some answers before I make the leap. If anyone can help that would be great. My major concern is that I will be using the Palm almost exclusively to edit and e-mail Excel documents and Im a little nervous about compatibility. Here are my questions: 1. I have an old Palm m515 with Documents to Go 4.0 and my Excel documents are locked when I try to edit them on the 515. Apparently certain formulas are unsupported by DocsToGo 4.0. In my case, I have formulas that reference other sheets in the file. Has this been corrected in DocsToGo 7.0? 2. Right now Im torn between the new LifeDrive and the T5 (with added Wi-Fi card). My primary use for the Palm will be in editing Excel documents and then e-mailing them using a Wi-Fi connection. Do either of these devices have a better feature set for doing this? Is the built in Wi-Fi card in the LifeDrive better than the Palm Wi-Fi card? Which one has a better processor? Screen size, resolution? Thanks in advance for any help!
