Allow me to throw in my humble 2 cents

I'm no Linux novice, and have no idea how to get command line working. It's been years since I coded anything, and I've since moved on to other priorities in my life.

As a result, I've learned to be clear about what I want my device to do. I bought an N800 for media playback (music and videos), VoIP (Skype, Gizmo and SIP), IM, and most importantly, a good web browser.

With Canola2, I have a great user experience for my media needs

With microB/Mozilla, I have a great user experience for my web needs, and since it does Gmail in all it's AJAX glory, YouTube

With Orb, I use uPNP to gain access to my primary 500GB media hard drive at home, allowing me to locate and playback/view and song/image anywhere in the house

With Skype and Gizmo, I have a choice of using either service provider across 2.75G/3G/3.5G and Wifi networks, and with this, anyone can call/IM me, anytime, anywhere.

I have a Transcend 16GB SDHC card in my N800, and plan to get another 16GB SDHC card when I return to Singapore in a couple of weeks. Combined, this gives me 32GB of space, which Vista/XP automatically recognize as flash storage -- No need for any fancy sync software to sync my music and videos, although I do re-encode my videos to optimize for size. My N800 has more storage compared to my iPod photo, and if it wasn't for the limited battery life of the N800, I'd have long retired my 30GB iPod Photo

My N800 connects to my Nokia E51, which also gives me VoIP, IM and a semi-decent web browing experience, and is a killer device in its own right.

The only real downside I have experienced so far is related to battery life, and i have solved that by toting a small Nokia charger and kept a Nokia car charger in my car. The iPod Touch and iPhones are not exempt from this problem as I understand that prolonged web browsing could limit battery life considerably.

All in all, I spend more time USING the N800 than FIXING it. Aside from the few foolish moments experimenting with beta software such as the Instant Messaging upgrade (I have since realised that Pidgin gets the job done for me), I have had few problems, and nothing that could not be resolved by a quick reflash. This is where I have learned that it is a good idea to backup your bookmarks, contacts and settings)

Would I be happier off with an N810? Certainly, but I also understand that it only had ONE SD slot, and until 32GB SDHC cards appear in the market, it means that I can 'only' have a max of 18GB on the N810. The N810, however, has two features that I would like -- a physical keyboard, and GPS, and I will probably pick one up as soon as I can get my hands on one back in Singapore or from Amazon.

The way I see it, A2DP is not an IF, but a WHEN, and in the meantime, I have no issues using a wired headset, which is not a bad idea since a BT stereo headset would impose more drain on the battery life.

Hope this helps your decision making, from a newbie's perspective.
