Even though I purchased and grew fond of the Nokia E62 and E70, I decided to give this smartphone a try due to my good experience with the SE W810i model.My first impressions on the first couple days were absolutely DISMAL from the numerous crashes that required taking out the battery to cut off the phone. After the 15th crash, I called SE customer service and calmly gave my opinion on the performance of this phone. By suggestion from the operator I downloaded the firmware upgrade from the SE website and must say that all is well. The technology packed into this phone is amazing, and not mention the eye-catching looks of the silver covering.The ability to input info via the qwerty keypad and the touchscreen/stylus is a HUGE draw for me, a former Palm pda/Treo 680 owner.Accessing WiFi and setting up bluetooth with my MacBook Pro was pretty simple, but synching the address book and calendar is a different story. In lieu of no Mac iSync support I am using a third party software called p990iCal to sync my calendar data and using bluetooth transfers for my address book vcards, and both methods work just fine.Navigating the phone does take some patience and time, but using the manual with good common sense is usually enough to suffice.The bright, crisp screen is relatively large compared to the Nokia E70 and the qwerty keyboard, though small, is a joy to type on with my thumbnails. There is one gripe about typing on this keyboard: I love the support for Quickoffice on the smartphone, for I am addicted to writing on the go with Word. Where the Nokia E70 and E62 shines concerning text processing on the qwerty is where the SE p990i rests on its laurels. The SE cannot keep up with my typing speed whereas the Nokias could without a doubt. After pressing each button there is a taskbar that pops up at the top of the screen showing the selected character being highlighted and then placed into the document body. This truly slows up the typing process...and if you keep typing as the p990 tries to catch up, it gets lost and inputs jumbled letters. I have disabled the predictive text feature, but that apparently only handles the words and not the individual characters.I have deducted one star for this reason alone.The screen that shows spectacular imagery in clear color cannot be seen at all in outside sunlight, so be aware of using this outdoors. The photo quality is amazing and the flash is very strong while the video quality is great but not stellar. The media player application plays mpeg4 video files that my Nokias were unable to play, and the music player and FM radio is great as long as you have good headphones(the speaker is in mono). I surely took advantage of the space I had in a 2GB memory stick I had used with my previous W810i model.The task manager is an absolute godsend! Instead if having to go through the menus to access recent apps you can go here and reopen them again! Voice dialing is good but must be programmed for each contact entry which the Nokias did not require at all. Handwriting recognition on the touchscreen appears to be the same as any other Palm device.This is definitely a neat little tech package for those who love gadgets. Downloading the firmware upgrade should alleviate any problems concerning its performance.Update for May 2007:I have long since this review sold my p990 device and returned to Nokia. I am currently using the E61i until my preorder for the E90 Communicator is fulfilled. The p990 was and is still a great device, but just not for my purposes. This is a real shame, for I will always have a soft spot in my techie heart for touchscreens and styli in navigating that p990. I just couldn't tolerate the inconvenience of no Apple iSync support and a slow Quickoffice Word interface in writing my poetry and blog entries. Nokia has provided reliable stability in both these areas and I plan to remain with them as a loyal customer. The p990 is still a capable device for what it can do, only as long as it is updated to the current firmware and can adequately meet one's needs.
