"You can't place a shortcut to a person"
You can by adding the Favourite widget to the home screen. You can then add up to 10 people to this list and the widget multiple times - one for work, one for family etc. You can also open your contact list and long press on individuals and mark them favourite - this will bring them to the top of your list whenever you write a message or open contacts again. The only problem is that you can't organise your favourite in any order you might like - only in the order that you added them to your favourites.
"you can't drop applications wherever you like."
You can to a certain extent by adding the Shortcut widget, but then you HAVE to select 4 apps to use. But putting individual app shortcuts is not possible.
"You can't set a shortcut to activate a particular setting, either"
You can for Wi-Fi, Bluetooth, Sip, to different menu shortcuts. Which one do you want that is missing?
"it won't use the spacebar to accept suggestions unless you change another setting"
Really, how? I have been looking for this and can't find it anywhere. Using the right arrow to accept the work and then hitting spacebar is a poor design.
"E-mail now uses Nokia's server-side Intellisync software, but for obvious reasons of security (Nokia knows your passwords) I didn't test this extensively."
This can be bypassed. If you reject the terms and conditions right at the end of the email account set-up the emails won't go anywhere near Nokia's servers. This also helps because you can send attachments larger than 2MB in size the latter imposes.
There are other fiddly little problems to the ones you mention in this article. In many menus if scroll to the bottom item and select it when you go back the phone automatically takes you back to the top of the list. Notes and files of this type cannot be scroll without first selecting and marking all the text. I can customise my home screen by long pressing the screen, but I can't do the same when inside menus. Why? Instead I have to click on options and then organise. I then can list the items in alphabetical order - instead you have to move each individual icon to the location you prefer.
Mail for Exchange crashes on replying when using Gmail. IMAP email doesn't work as push email, so if your settings are set to retrieve soonest the app won't work until you open it. These things have been smoothed out over years by Nokia so why they should stop working properly is anyone's guess.
