For what it's worth, here's a couple of observations applying to both lvm and TH14's interest:
Read Dwinget's post under your questions - he's right about Word/Excel stuff, Sunrise, Plucker and DataViz!! To add just a little bit . . . .
I have not read a single "e-book" other than pre-made ones (for testing purposes only) from TealPoint. I would defer to dwinget for instructions on those - and I'll be paying attention, believe me! I have tried using TealAgent combined with TealDoc for downloading "e-book type stuff" and to be honest wasn't very happy. I would say Sunrise is better and easier.
As for "non e-book document handling," I've long been a Tealpoint fan, and bought TealDoc 2 years ago "because Tealpoint are great." Didn't use it much.
HOWEVER, their latest version allows EDITING of text files. I now do everything in plain text - I bought Fastwriter and dumped it. I bought WordSmith and dumped it. I now use TealDoc for letter writing, memo pad replacement and other stuff like "reference text documents" stored on an SD Card.
The beauty of TealDoc is that it works flawlessly with "TextSync," free from sourcefourge. TextSync does the same as any conduit-based "syncing" of MS Word such as WordSmith, Word to Go or FastWriter - but in plain text. The app on the handheld is a 400 byte (0.4k!) "stubbie" for reference; it takes up around 2.5MB on the PC. Documents in RAM are automatically synced unless you remove from the desktop conduit - but that DOES NOT delete them on the handheld (very handy).
I maintain "Blank 1, Blank 2, Blank 3" on the handheld for STARTING new text documents in TealDoc, then renaming them to the correct title. TextSync SYNCHS that information, and then REPLACES the blank document as well, so you always have "blanks." You can edit the documents on the PC and they appear with changes made on the handheld. Syncing is very fast - couple of seconds.
I still use Sheet To Go for spreadsheets (dataviz), but Dwinget is a big Sunrise/Plucker fan and for good reason - I think for downloading webpage information Sunrise/Plucker is hard to beat. Right now it's freeware, but the developer will soon be DISCONTINUING Plucker support and selling his own handheld viewer. New betas of Sunrise are coming out at a rate of 1-2 per WEEK as he "cleans it up and makes it perfect."
It all depends on what you want; I made the decision that for MS Word based documents, reading AND writing, that plain text, TealDoc and TextSync served MY NEEDS best. The downside is you don't have "Word" formatting, but I no longer have conflicts between WordSmith and TealDoc "fighting" over a plain text document, and I found WordSmith's desktop interface to be intrusive and very hard to delete. It's messy. You also don't have the option of as many text editors, pop-up editors etc whereas TealDoc will accept and work with "most or all of them."
If I decide my written "stuff" should be in MS Word, I simply copy and paste to Word and print a letter or save as Word Format. I've got dozens of reference material based text files taking up perhaps 35k on the card - as opposed to 600k of RAM, 5MB on the desktop, 150k in Word Docs in RAM and 150k in "fonts," whether they be for Word 2 Go or WordSmith. Just seemed like an unnecessary and bloated waste of space to me as opposed to simple, plain text.
If the e-book you're wanting to read is already formatted, TealDoc would be good. If you're building your own HTML stuff I found Plucker to be easier. For stock "MS " NON E-BOOK material, Documents to Go is the best for Spreadsheets but WordSmith does offer a lot for Word Document handling.
I'm going to PM or email dwinget regarding Suncrise/Plucker since I've tried it twice now (2 different versions) and also "auditioned" iSilo. I would say between Suncrise and TalDoc you'd have it pretty much "handled," but I'd like dwinget's input on "tips and tricks." I read his TDoc question and my eyes glazed over . . . I'm just not SURE to be honest, and had an example this morning of where Sunrise might really help me more for HTML. I'm sure TDoc can do some or all of it - I'm just not sure how, I'm sorry to say.
