We know that E71 has faster CPU clock than E90. Nokia E71 has CPU Clock Rate at 369 MHz, while Nokia E90 CPU Clock Rate at only 332 MHz. Does that mean E71 is going to be faster than E90?
Michal Jerz over my-symbian forum has great great answer for this question:
The Freescale processor in the E71 has different architecture than the OMAP2420 processor in the E90. It doesn't make much sense to compare just the clock speed of two different processors.
It's like with Intel and AMD processors. Even tough they're both based on the x86 technology and are compatible (just like the E71 CPU and the E90 CPU are both based on ARM11 technology and are compatible), differences in their internal architecture cause that e.g. some AMD processors are faster than their Intel equivalents at LOWER clock speeds.
There is also one important additional difference between these CPUs: the Freescale in the E71 is a single-core CPU whereas the OMAP in the E90 is a dual-core CPU. The E90 processor has separate core to handle the baseband (telephony and network related tasks) and separate core for applications. The E71 processor has only one core, dealing with both network and the OS. So while (thanks to its faster clock) it can sometimes be faster (e.g. when there is no network/telephony activity to handle), with such activity in the background it may actually turn out to be slower. And it's worth noting that some network/telephony activity happens almost all the time, even if you're not connected to the Internet or making a call at that moment. The phone constantly updates its location, switches between neighbouring base stations, monitors their signal quality, checks which services are available (GPRS, 3G, supported call encryption algorithms, etc). It only doesn't do any such operations in Offline mode.
Last but not least, the OMAP in the E90 has graphic and video hardware accelerator, missing from the Freescale. That's why you can e.g. run the full OpenGL ES version of Quake on the E90 but not on the E71. That's also probably why the E90 can record high quality VGA/30 fps video while the E71 only records QVGA clips at some poor 10-15 fps.
Long story short, the OMAP2420 is definitely more powerful than the Freescale in the E71, so don't worry, you didn't waste your money.

Best Taskman vs Handy Taskman
"im92109210", my-symbian forum member, have a very nacie review about Best Taskman and Handy Taskman. Both application have the same price tag of 9.95$ and they both provide the basic function of dealing with open applications very similarly and professional.
Both application, as the name suggests is a task manager. It allows the user to handle open applications and allows them to switch to another application, get their information, close them, etc acting as a (Ctrl+Alt+Del combination) option for Series 60 3rd Edition. It does have a few rivals, but being the latest version released it was worth testing out.
For a complete review you can read here:
Best Taskman Review
Handy Taskman Review
Comparison notes with Best Taskman
Since these two applications are competitors and do the same function it is fair to have a comparison:
1) Function-wise, Best Taskman has more features such as:
Quickstart (Handy has Recent applications)
Alt+Tab type of application switching
Autostart (Handy is actually opened when ever Menu is pressed and held)
Ability to see hidden Processes
Ability to see Installed Applications.
2) When selecting “Close all exceptions” on Best Taskman allows more than one application to be selected at a time.
3) Once Best Taskman was opened, pressing Menu would NOT open the menu unless the application was closed or hidden, which rendered the Menu button useless. Handy allows the button to open the menu whether the application was open or not.
4) Best Taskman uses more icons than Handy Taskman, and has bigger font and icons for better usage and visibility.
5) Handy Taskman has lesser features but seems more built together, Best Taskman has a lot of features but is not very nicely organized and setting it up and using it could be a bit harder than Handy Taskman for some people.
I was expecting towards the end I could say that one is better than the other. Unfortunately, although both applications do a similar job, they seem different. Handy Taskman is a very basic task manager and does JUST that. That makes it less complicated, and has less key presses and shortcuts. Best Taskman has more features but lacks the “Recent” list of applications, but compensates with “Quickstart”. It seems that they fit for two different kinds of users; one that wants a full task manager with extended functions such as “Quickstart”, quick switching, processes, etc. and the other is for the user that wants a very simple, basic task manager. Both are very good programs for the same price, but if I had to choose one of the two, I would personally use Handy Taskman.
Even though I rated Best Taskman a high 9/10, I would rate Handy Taskman a 9/10 also. It has a little less functions but does the rest very simple and very well.
The program tested was a trial and not a full version although it was fully functional.
The trial and full version can be found at the My-symbian.com Online Shop

Why Nokia Change Communicator Interface to S60 v3?
In new E90 Communicator, Nokia decided to switch user interface from S80 to S60 (3rd edition). I just wonder, why they did it? Doesn't it make developer have to remake program with S80 UI specialized for E90? Some E90 user also say that S60v3 have litle compatibility problem with E60, especially for games. So, what is the real reason on this decision? S80 UI is so bad?
I asked it to my favorite forum, and got some good explanation:
"The S80 user interface is basically better suited for a widescreen than S60, which was mainly developed for one-handed use. But it is a huge effort to develop a platform, so Nokia apparently found it necessary to concentrate only on S40 and S60 development and thus abandon further development on S80 and S90 (Nokia 7710).
Also feedback from operators and developers probably forced this decision. Operators want as few content platforms (e.g. for multimedia) as possible and developers want as big installed base as possible for their applications".___ BentL
"It's not the UI itself, more about the backend. Cost of developing S80 to support new standards for hardware, security etc. Shame Nokia could not do it, but from what I can tell, if they had developed S80 all the S80 apps would have had to have a major rewrite anyway. So you would have started out with zero 3rd party apps. It was probably too late for an S80 rewrite at this stage. At least this way, you get access to the current S60 library.
Though I do wish they could have carried more of the S80 power features across somehow. You get the constantly dumming down feeling from what I have read (don't actually have the E90 yet).
My main gripe is that S60 does not seam to have range/power apps that you can get for the Windows Mobile Platform or the Palm Platform. Hope that changes with more powerfull devices like the E90. Looks like it will be selling really well, so that should encourage development..." ___ Zuber
Based on this comments, I think the real reason is not because S60 v3 better, but because it's cheaper, easier, and more practice to have less UI interface. So what do you think? Nokia give worse UI on E90????
