There lots i love about it, the positive stuff outweights the negative stuff by far, but since the good side isn't the topic of the thread, here are some my complaints

* Builtin speakers aren't even nearly loud enough

* Hard to make the battery last with intensive use

* Doesn't have multitouch (i'm not talking about crapacitive, resistive multitouch is far superior)

* System (and some programs) can get bogged down and somtimes even unstable after running uninterrupt for too long like desktop Windows (might have somthing to do with all the hacks i've applied, the amount of stuff i have installed and all the messing around i do etc)

* The position of the charger and headset plugs

* The lack of a builtin antenna for the FM tunner

* The FM transmitter doesn't seem to be strong enough (might even be weaker than the reported value, though this might be only with my device)

* The screen is nearly unusable under direct sunlight even at maximum brightness

* The bultin speakers positioning and orientation (if i hold in the most confortable position for typing with two thumbs and having access to the upper buttons (volume/zoom and the camera shutter) my hands cover the speakers grills making the already low output get even lower; and the speakers seem to be facing the backside of the device, it sounds louder from behind)

* The slow down when answering calls

* It doesn't have a five way input (somthing i think would rock was if it had a little "glass" nub by the right/bottom side of the screen that used the same (or similar) touch technology the screen does, the more you press on each on a side the faster it would move the mouse cursor, and if you pressed it straight on the center it would "click" the mouse, and an alternative mode that would work like a trackball moving the mouse cursor by how you rub your finger on it and click (as dragging) like a trackpad (a tap to click, tap-hold to drag), and it wouldn't be hard at all to convert that input into joystick input for games and stuff

* It has closed parts (hardware and software) that would allow us to push the N900 even farther if they were open

* How Nokia seems to not have taken the N900 seriouslly enough, kinda feels like what we bought is just an internal proof of concept and we signed a waiver liberating Nokia of any responsibility to the customers (i know things aren't really this bad, but it does feel like it)

* Lack of a 3 axial magnetometer (a compass)

* Crappy quality of the face camera even when a program (like Skype) tweaks the parameters for a better result

* The diminished quality of some photographies taken with flash

* The camera module is less flexible than the ones of similar quality on other Nokia devices in certain aspects (can't crop the image at the image sensor level, usefull for things like foveal imaging and non-lossy zoom among other things)

* A few keys are loosing the opaque black layer, leaving a transparent hole in them

* It only got 3 rows in the keyboard (it isn't as bad as it initially sounded to me, but having a dedicated number row would be great)

* The bottom row of keys are too close to the edge making using them in some games awkward

* Not enough hardware buttons (buttons to answer and dismiss calls, to call the menu, shortcuts to programs etc)

* It is awkward to use the top buttons and the keyboard at the same times (like when playing a first person shooter)

* The keyboard isn't as bright as it could be (i know it could be brighter 'cause of the transparent holes in some keys i mentioned above)

* Its too easy to lag the whole device ( like when upgrading programs, copying large files etc)

* It heats up too easilly

* I would rather if the black plastic on the case was mate black aluminum

* The backstand isn't wide enough leaving the device in an unstable position (IMO the ideal shape would be a trapezoid, so it would also work for placing the device in portrait mode)

* The vibrator motor doesn't got enough torque, and it wouldn't hurt to have a higher top speed and a heavier off-center weight either (it isn't capable of reving up to full speed fast enough for the smaller patterns like the default one for haptic feedback for touching the screen); also it probably would help if the motor reversed direction on each subsequent run so a runs with shorter pauses between them would feel like indenpent instead of accumulating the momentum of the previous ones (i'm not talking about the pulse modulation used to control the speed, i'm talking about the burts of pulses, like when you tap the screen several times really fast or when the pattern itself is set to repeat)

* Many programs got GUI elements that are too big or too small, and some even combine the two extremes by plancing big elements together in a small space making them overlap and have parts hidden

* Digital and analog TV tunner supporting all the more popular standards would be nice (don't forget the builtin antenna)

* The IR part is just an emitter and not a transceiver compatible with irDA (somthing i've just thought of, it would be awesome if the IR "port" was next to the main camera and we had the ability of photographing and videoing in infrared without visible light)

* It would be great to have the touchscreen also feel proximity without touch to allow for things like moving the mouse cursor without clicking on things ("hover") and using hand/finger waving gestures.

* I don't like that when programs slow down things like the audio from keys and screen touches also lag, also i hate how keypresses get into a pile up if i type faster than the program can handle (when that happen the result looks like one key was held down for some time (producing it's alternate character, the symbols and numbers) and most of the other keys had never been pressed and then the last keys are pressed. I much ratter the way it works(or worked) on PCs, after the input buffer has been filled up faster than the programs can handle the machine will emit an error beep for each key pressed that can't fit in the buffer discarding it (it doesn't need to be an audible feedback, the N900 got a vibrator and the status LED that could be used to provide the feedback), i've never lost several words of typing on a PC like how it happens on the N900.


* The issue with lack of space in rootfs

* TV-out only in RCA quality

* No up-to-date Flash

* Doesn't got official Java and J2ME support

* No way to run Symbian programs nativelly (i'm not talking out cross copiling progs that use QT)

* Nokia should have released a FOSS OpenGL to OpenGLES wrapper with the N900

* I know it helps with battery life and heat production, but using a ARM instead of a x86 processor means lots of binnaries avaiable out there aren't compatible

* Doesn't come with official support USB OTG (automatic switching to and from Host mode and stuff)

* A mic array to filter sound by the position would be nice

* The interference between bluetooth and WiFi



There are probably other things that i'm not remembering right now
