Hello, new N800 owner here. I have a lot of questions, but I'll just start with them one-topic-at-a-time. Here's my first topic, about memory management:

I have just purchased a SanDisk 2GB Extreme III SD Card specifically for use with the N800 and placed it in the internal expansion slot.

1) Was this the fastest and best option for an expansion card? I read that MMC cards might be faster than flash memory, but the specs on this particular brand/model of card seemed to outclass the fastest MMC I could purchase. Anyone know of a better option?

I have already expanded "virtual" memory to this card by the full 128MB allowed via the Memory Control Panel.

What I would like to do with the 2GB card is to use it for *applications* that I install, so as not to take away from the internal flash memory storage. However, when downloading stuff, it always seems to install to the internal memory and I don't have the option to place it on the expansion card (like I would on, say, a Palm device).

2) I found some advanced instructions about doing this for the Nokia N770

... Which approach is better? Do these apply to the N800? Has anyone tried them and confirm they work? I don't want to goof anything up!

2a) These all have really technical instructions (installing a .deb file? howzat?) Is there any nice, neat GUI tool for this?

3) Would it be smarter to put the included 128MB mini-SD card into the insternal slot and use THAT for the virtual memory swap file? (i.e., cheaper to replace when it wears out?)

4) How much real-world usage would have to occur before I "wear out" a flash card by using it for virtual memory?

5) If I use the 128MB card in the internal slot and dedicate it to virtual memory, and use the technique I found for putting applications on the external slot and the 2GB card, will my Nokia freak out if I remove the external 2GB card for those times when I want to exchange/load files on the PC?

Thanks in advance. I'm sure I'm asking stuff that's already been answered but I couldn't easily find it and I'm hoping that this "silly question" will put all the answers in one place.
