I've been an AVID Blackberry user since the 957 days. A few things have always annoyed me, but I persevered because of the at least for me great calendering and contact management and of course the email. That is until recently. Three days ago my Pearl died and a buddy of mine lent me his black Nokia e50 which runs on Symbian s60 v3 platform. It has opened my eyes!

Thing I can now do I couldnt before:

• Read, EDIT and ACTUALLY SAVE documents and attachments in Office formats

• Add a myriad of very helpfull to trivial apps to keep me busy and on task
• even more rubust contact management
• sync just as well with all my Mac computers as BB
• sync with bluetooth FINALLY!
• I can use data on a prepaid overseas SIM when i travel. Not so with BB
• Change the whole system look with great and abundant themes

• AMAZING HTML web browser wityh an actual mouse curser

Things that are on par for both

• Both have 1.3MP cameras
• both are roughly the same size
• both are EDGE only Quad band

I thougt I would miss these things from the BB but didnt

• push email Its great and all but the s60 email is very powerfull and pulls my email every 5 minutes. which is good enough for me
• Suretype. I'm just as fast on t9 as suretype. I';ve timed it
• The web browser. S60 browser OWNS BB
• great battery. I was on the Nokia on a 3 hour and 50 minute conference call and i still had 60% battery left after it was off the charger for 5 hours prior

Things I DO miss about BB

• It's a really easy and basic OS and therefore a little easier to navigate. I find myself having to look for settings and things on the Nokia. As I familiarize myself with the s60 OS I'm sure that will change.

Wow, I did the reverse of what you did. I left my Nokia N80 for a BB Pearl from T-Mobile.

At least in my experience, the N80 was...

Cons:
1. Slow (compared to my Pearl) even though I flashed the N80 to the latest available OS
2. Always runs out of memory, whether I am using the standard browser that came with it or Opera/Opera Mini. Though to be fair, the N80 had 40MB of internal memory vs. the Pearl's 64MB.

Pros:
1. Wi-Fi! 3G/UMTS (though I only get EDGE w/T-Mobile)
2. Ability to open and *edit* Word and Excel

All in all, I'm happier with my Pearl and can't wait for:
1. Pearl 2 w/Wi-Fi
2. DataViz to come out with Documents To Go for BlackBerry

Of course, to each his/her own.

Nokia does make some nice devices. They are porbably one of the manufacturers I would use should I give up my BlackBerry.

I'd also like to add that I hated having to use the trackball to scroll through word options on the Pearl instead of using a button on the keypad like i can on the e50 That sped up my input vastly.
