Nokia N Series N810 256MB, Wi-Fi, 4.1in - Silver

Love: Screen is BEAUTIFUL! Construction is solid. Runs LINUX!!! Fast WiFi and automatic connections. Calendar app is awesome, and easy ToDo apps make wifey happy. ;) and games, games, games. (try pingus, Hex-a-Hop and numpty physics)

Like: You only buy this device ONCE. ALL THE SOFTWARE IN THE APP STORE IS FREE!!! Good sound, tiny qwerty keyboard, fast WiFi, touch screen or stylus. Canola application alone makes this device worth more than the going price as a media player. Kickstand for video, can pair with a BlueTooth keyboard for efficient note taking (though If you're going to buy a keyboard anyway, look at the older N800 instead because of price, memory capacity, and FM radio tuner). E-book reader, PDF viewer, desktop applets like: RSS, weather, ToDo/calendar. Good batterylife, customizable UI, phone tethering. Decent free GPS with free map updates. Also VERY hacker friendly if you are, or want to be one. Standard Nokia charger so you may already have a spare or 3. Multitasking, great sound quality, fantastic screen and on-screen keyboard (not to mention slide out keyboard) are all MUCH better than iPod touch or iPhone and is far more readable. The provided car kit is also good.

Dislike: It is slow compared to a netbook, but speed is about equal to iPhone. Some of the best apps are not installed by default. Video is not available in Skype. :( Package manager can not que multiple installs like other Linux distributions, (though it can update multiple?) so setup can take long enough to get your wife upset with you. GPS acquisition takes forever each time you first start it (this is the single biggest disappointment). The protective sleeve is welcome, but not ideal. Too much sample media (songs, videos, pictures, PDFs etc...) eating up (solid state) hard drive space. Oh yeah, the camera stinks.

Bottom line: If any of the following apply to you;
a. like to tinker
b. like Linux (O.K. Almost nobody likes linux. Most people Love it or hate it)
c. like to own a device instead of it owning you
d. like Free app stores
e. like to be different
f. like a device that is not a phone
g. like a device with a community
h. can not afford or can not wait for the new N900 later this year
i. want to participate in the Open Maps Project
Then you probably should own one of these.

The Nokia N810 is a great internet tablet with a slide out keyboard and touch screen, it has wifi and the internet connection is better than my laptop, there are hundreds of applications and a whole community of developers and users dedicated to supporting it and are willing to offer help and advice.

This is much better than a PDA. It is like a small pocket size netbook or laptop computer. It does more than you would expect, you can customize it to fit your needs. There seems to be an program or application for almost anything you would want, it plays music, movies, word documents, calendars, to do lists, e-mail, chat, skype internet calling. I love this device. The only thing that it does not have is a sim card to make it a cell phone, other than that it is practically a perfect device (the new N900 is also a phone but costs a lot more).

I also have the N800 version without the slide out keyboard, it is cheaper, has the same operating system and does pretty much everything the N810 can do if you don't mind having just a touch screen keyboard. And both have a small kickstand so you can stand it up for easy viewing.

Weight of N810 exceeds that of its predecessors, though insignificantly. 226 grams is much in comparison with the mobile phones, however it is little in comparison with any UMPC available nowadays. The weight could be a little bit smaller, but for the metallic front panel of the handheld and the battery cover.
Coming back to the device dimensions, first of all they are caused by the screen size - a 4,1” diagonal that sports a resolution of 800х480. It is the best screen among all PDA-phones, the image quality being maximal, the view angles excellent.
The arrangement of control elements on the front panel of N810 essentially differs from that of N800. The navigation button with the OK label on it is unavailable when the Nokia novelty is closed. Only two keys are left on the face panel: the lower key is used to return to the previous page of the internet-browser, to switch to the previous view in applications and keeping this key held shuts the running application. The key "home" calls upon the menu of the launched applications (there is an opportunity to shut an application), holding the key allows to return to the desktop, keeping it held once again switches to the latest launched application. The objective of the camera for video calls is found near these controls. The luminance sensor is a novelty for Nokia tablets as well. Employing it not only increases the time of independent work, but also allows working comfortably both in the darkness and in a well-lit environment - the screen brightness is adjusted automatically.As well as with N800 the battery capacity makes 1500 mAh, but the battery model itself is more up-to-date, the battery charge level is metered more precisely. The battery lifetime is an unquestionable advantage of the new gadget. As for this parameter, it’s the most "durable" device in the market.
The N810 desktop is divided into three working areas. On the left there is the Task Navigator the bottom part of which displays launched applications and the upper part hosts the icons granting quick access to the Browser, Contacts and Applications. Contacts and Browser are replaceable and Applications can be customized.The status bar is found at the top of the screen, displaying service indicators like the battery life meter, the screen backlighting and the sound volume levels, etc. The user can customize the order in which these fields follow or remove some of them from the screen completely. The indicators showing the battery charge, the connection and the GoogleTalk service status cannot be removed from the status bar.The main part of the screen hosts the area for desktop built-in applets. The applets can be toggled and dragged freely at any time. Some of them can be resized. The new version became more easy-to-use - they aren’t locked into position, can be moved at any moment and can overlap (the transparency effect is employed). The desktop applets grant quick access to the applications, RSS-news headlines, clock, weather forecast, Internet radio, etc. N810 enjoys the latest version of Mozilla Firefox. The Flash 9 plug-in provides for a full-blown navigation practically through any Websites. The AJAX full support is quite to the point. YouTube, Google Docs and Google Reader - all of them can no problem run on N810.

+ Excellent screen
+ Long battery life time
+ Compact dimensio
- Necessity of video conversion
- Screen gets glared in the sunlight

This tablet is the best tablet i have had. I have had many Palm devices and HP pocket PC's back in the day and i have had the iphone and ipad but the web browsing experience of the N810 is still better than everything else! This tablet renders webpages as you would see in a desktop and not the mobile version. It also runs flash! It can run youtube in desktop mode! Its also possible to make this tablet dual boot to Maemo and Android. The maemo OS is a flavor of Linux and is built to multitask. Its also an excellent multimedia device! It does run skype and Fring! It has Wifi and can also tether via bluetooth. It has a miniSD slot for expandability. Please bear in mind that it is a device for entertainment and browsing and not a PDA. It also has GPS built in.

The n810 has the same CPU/ram as the n800 (a TI omap2420), but since the price was so similar I had to go for the n810.

The n810 is much slimmer and nicer to carry then the n800 which had an awkwardly large camera housing.
The dedicated slide-out QWERTY on the n810 can reduce the amount of task-switching the weaker 800/810 CPU needs to pop up the on-screen touch keyboard, as well.

wrt the ergonomics, the top-located locking slider is hard to reliably depress with your right hand, but can be easily operated with the left.
thirdparty 'autolock' software is available as well to automatically lock and unlock the screen/keys via the ambient-light sensor introduced with the n810 model. Just by putting the handset in your pocket or taking it out!

Some additional quirks with the hardware,
even with a properly patched/alternative GPS daemon and the optional agps internet assisted lock acquisition the integrated GPS receiver is very slow to get a lock. (60 seconds or so)

it is useful to have, but not amazing.

and of course with the n810 we lack an electronic compass or accelerometers :P
