Hello, I have been doing some research into the N810, and have already found some answers to my questions below, but not quite as much as I wish to know, so I am hoping for some help. I plan to order from Amazon in the next few days (they seem to have the lowest price at the moment).

1a-Will a 16GB microSD card Class 4 or greater work on N810?

1b-Can an SD card be partitioned? It cannot on windows. The purpose is in the following question.

1c-Can all cache memory and temp files be directed to the card, as well as all programs and data, so that internal memory is protected/accessed less? Separate partitions is even better than separate folders in the same partition.
I know doing this will not make a device without a hard disk run faster, but in my experience, it will protect the system files better, at least on a windows machine.

1d-Can the sd card be automatically mounted and unmounted (like in Windows), to avoid card corruption/unavailability already reported on other threads?

2-How durable is the N810? I forsee some banging and dropping. I am very concerned about the apparent absence of a screen shield, like Palm devices have.

3-Is there an external battery charger? In my experience using different devices over the years, charging on the device itself reduces its life.

5-I know the N810 connects to a network wirelessly, but are there practical options for doing so via a wire? A wire is normally faster of course, not sure on the N810.

4- Is there any wireless portable keyboard that works with N810? I know the issue is drivers. I checked Belkin so far, no luck. I heard a wired keyboard is possible, but I have not looked into that yet.

5a- Is it true that the new N900 coming up has a smaller screen than that of the N810? That, the fact that it will still have microSD, and being a phone, made me lose interest in it. I cannot see what could possibly be better about it.

5b-I read that the N900 will multitask, does that mean the N810 does not? I thought every Linux distro does.

6-I have seen the videos showing people taping around on the N810. Is it possible to run the device exclusively with keyboard shortcuts? They are faster in my view.

7-Can one copy and paste between programs, like on Windows? I ask because this is not possible with my WM5 “smart” phone.

Thanks in advance for any help.

If it is placed in a Micro to Mini adapter, yes.

Yes.

Under what conditions?

Quite.

There is not an official Nokia one; however, there are inexpensive, third party models available on eBay.

See: USB to Ethernet Networking

Any Bluetooth HID keyboard will work. Bluetooth SPP keyboards can work, but not as easily.

Bluetooth HID keyboards do not require drivers.

See: USB Host Mode

While there's been no official announcement of a Maemo 5 device yet, it does appear that the next device will have a smaller screen.

All Maemo devices multitask.

No, though they keyboard and hardware keys may be used to access many functions of the device.

Yes.

Wow, thanks for the quick answers!

Well, pulling the card out to copy files and programs from the desktop, basically. I don't wish to have to do this manually by typing commands. Some threads here appear to suggest that the N810 does not like having its card pulled out normally.

I am wondering if the pouch has a screen cover hard enough to protect the device from a moderate direct blow to the screen, like what a Palm device has.

You won't need to type commands.

When you open the MiniSD slot door, the system will attempt to automatically unmount any card within. If you have an application using a file on the card, the system will fail to unmount the card, and a warning message will appear on the tablet's screen. Should you remove the card anyway, bad things could happen.

The system will automatically attempt to mount the card in the MiniSD slot when the card slot door is closed.

The pouch is not hard. Should you want protection similar to the hard flip covers on Palm devices, you'll need to look at third party solutions. For suggestions in that area, you might try searching for old threads here, as cases have been discussed frequently. There's also the chance that someone may wander in here to provide an opinion.

I don't use a case, so I will bow out at this point.

In addition you can just attach the USB cable to the PC and Maemo will unmount the card for you and mount it as a flash drive in windows. The same conditions apply - it would not unmount it if it is currently used.

N900 has better processor, a graphics chip, and more ram. I would call that better...

A graphics chip? Is that really needed? I guess the additional memory cannot be added to the N810, huh.
Doesn't faster processor = shorter battery life? That's one of several reasons why I don't want the phone.

I guess without returning to full sized SD cards (N800), a smaller screen, and having to deal with a phone on the device, I feel a bit underwhelmed about the additions (for the reported possible high price). But then I have not yet used a N810 to know if I would be jumping for joy for the improvements. As it is, the screen on the mockup of the N810 I saw at a store already seemed a bit too small for my eyes.
