(1) For files larger than 2 Gb: make sure your PC can handle this. If you use WIN2000 or XP with file system NTFS (default) you are OK.

(2) Main differences between the version for Pocket PC/Windows and the version for Palm are:

TR3 Palm misses html table support
(tables will be shown but will look a bit unorganized) and also has no unicode support
(no foreign language transcriptions and advanced math symbols).
