First off, I just bought an N800 off of eBay, and Reason #3 as to "Why I bought a N800" was because of this site! So thank you, already, for all the information! I am excited to learn with you and eventually help teach. (#1.Price to Power + Portability ratio, #2. Hackability/Versatility/Dynamic applications #3. Support/Community)

I searched the forum and did not find anything to what will be "My first of many questions". I'll try to make this succinct:

When coming upon a new application or web based service, and they say things like Windows/Palm/Mac compatible, but they mention nothing about Linux, does this mean that I should just leave it alone and keep on walking? Or is there a work-around to getting it installed and working on OS2008 (N800)?

For example:

This pages says the following:

What are Yahoo! Autosync’s supported PIMS and Systems?

PIMs:
Microsoft Outlook 2000/2002/2003
Outlook Express - 5.5 (on Windows 2000 SP4), 6.0 (on Windows XP)
Palm Desktop 4.01/4.1/4.1.2/4.1.4/6.0.1

Systems:
Windows 2000 SP4
Windows XP Pro SP2
Windows XP Home SP2

... And further says this about the program:

What devices or programs can I sync with using Yahoo! Autosync?

You can synchronize your Yahoo! PIM data (Address Book, Calendar, Notepad, To-Do List) with the following:

Microsoft Outlook 2000/2002/2003
Outlook Express - 5.5 (on Windows 2000 SP4), 6.0 (on Windows XP)
Palm Desktop 4.01/4.1/4.1.2/4.1.4/6.0.1

Lets say I wanted to over-the-air (without using another computer) sync my Yahoo information with my N800 (OS2008)... would this be possible with (or without) some hacking?

The mirror question to the above: If an application/service includes 'Linux' in the list of 'system requirements', does that guarantee that it will work on the N800 (OS2008).

For example: with the browsers on the N800 (OS2008), do things that incorporate (formerly Google) Gears work with OS2008 browsers?

I assume 'yes' because of what Google says here:

Installing: System requirements

To use Gears, you'll need one of the following:
* Microsoft Windows XP or Vista with Firefox 1.5+ or Internet Explorer 6+
* Apple Mac OS X 10.4+ with Firefox 1.5+
* Apple Mac OS X 10.4.11 (or higher) or 10.5.3 (or higher) with Safari 3.1.1
* Linux with Firefox 1.5+
* Microsoft Windows Mobile 5 or higher, with Internet Explorer 4.01+

The following devices are currently not supported:

* Samsung i320 and i320N
* Orange SPV C600
* Motorola Q

Again, since this is my first post, I feel obliged to show my affection for this site! Thanks so much for being an active community. It's been great to have any whim of a question answered with a quick search!

... I feel as if I already know so much about my N800, and I haven't even 'met' it yet! Perhaps the closest I'll come to knowing what it is like embarking on an arranged/mail-order marriage!
