Hi, I have exactly the same problem. I received my N900 for Christmas 2010, so it's not exactly old, and it was pre-loaded with the latest firmware (I'm told). My problem is that it's soooo very slow, especially with the call app. Sometimes I might be writing an SMS (wifi off usually, no other apps open) with the keyboard open, and if a call comes, I snap the keyboard shut and try to receive the call. Usually the caller stops trying to call before I can even answer, because the screen just goes black and does not respond. Just today I've had to calls go into voicemail because even though the phone was in my hand, I wasn't able to answer. Same thing with switching apps. Usually I only have my email client open, and an SMS open, and trying to switch between those two is a bloody nightmare! The screen either goes black or doesn't respond to touch. Usually the email client will time out and ask me to force quit the app. Same with the browser and app installer. I have tried uninstalling all apps and themes that I don't actively use to no avail. The application manager takes up two minutes (at least) to load up, and is slow at installing and uninstalling anything (especially uninstalling!). The browser isn't slow in and of itself. I usually don't have the wifi on, or any apps running, and it still manages to be slow. The issues shouldn't be with the amount of widgets running as the N900 should be designed for heavier use than I'm subjecting it to! The N900 is only snappy when I have no applications open and I'm switching between the various desktops. As soon as I launch _anything_, I get problems. Sorry to be such a moan, but I do hope there's a fix out there for this!
