Let's get the "swearing" out of the way first: when my Psion 5mx died (there, I think I got away with it), I got a Pocket PC because I didn't fancy the Palm interface. At that time pretty much every PDA was touchscreen. (Psions weren't being made any more, and Smartphones hadn't quite arrived on the scene.) I stuck with it because there was no alternative, but I hated it. QWERTY on-screen keyboards were fiddly and took up too much of the screen. Handwriting recognition was hit-and-miss. When writing anything, punctuation was a nightmare whatever input method was used. I tried a number of innovative input methods, but never found anything I could get on with. I swore that buttons in general and QWERTY keyboards in particular were for me.
I switched to an E70 (with the fold-out gull-wing QWERTY keyboard on either side of the screen) as soon as it became available, and then an E90 within weeks of its initial release. The E90 is still the device I use. However, there are some things (web browsing in particular) that simply work better with a pointing interface (generally implemented using mouse on a PC or touch on a phone). On a PC in most cases I'd much rather use the keyboard shortcuts than the mouse wherever possible and sensible, but there are still things where a mouse is more appropriate - web browsing being the most obvious.
The issue with most hand-held devices is that because of restricted space, manufacturers have to try to force-fit one or the other input method for all types of interaction, i.e. using a D-pad / joystick for things that would be much easier with a pointing device (such as a mouse, finger or stylus), or on touchscreen devices using on-screen entry methods for things that would be so much easier with a physical keyboard.
I'm holding out for the N97. My requirements are more geared to N-series than E-series machines (heavy Podcast downloading and listening for the daily commute, occasional music listening, and who'll deny it's always handy to have a camera and video camera about your person). I also want a wide screen for comfortable and natural e-Book reading and web browsing. I do occasionally use my E90 for email (I use the Google Mail app for access to my gMail account) but in reality it's rare that I need to get access to email when I'm not near a computer. I have been happily using Goosync for Calendar syncing with all my Google Calendars for quite some time, and have just (yesterday) synced all my contacts using GSync (now that Gmail finally has the capability to merge contacts!)
So far, there has been no machine that meets all my needs (basically multi-media, with a large portrait/landscape screen and QWERTY keyboard). I haven't had an opportunity to try out an N97, but I do plan to get one when they're released, purely because it's the best fit for what I want out of a smartphone. The lack of the Podcast app on non-Nokia phones makes anything other than a Nokia a non-starter for me for now. I'm apprehensive about how many of my numerous 3rd party installed apps on the E90 will work with S60 5th edition, but looking forward to finding out. Hopefully the 5800 will help the list of fully compatible apps to increase by the time I get my N97.
Maybe a capacitive screen would be better, but the slow typing speed on resistive will be offset for me by the qwerty keyboard anyway. My E90 is an expensive device, and as a girlie I often don't wear clothes with suitable pockets to keep a phone in, even if I wanted to. I'm used to keeping my E90 in a case, and I fully plan to do the same with my N97 when I get it.
It'll be interesting to see whether the arrival of 5th edition will prompt a revival of the old UIQ Sony-Ericsson P9xx (?) style phones with the flip keyboard partly covering a large screen, or perhaps N95/N96 style sliders with a touchscreen and slide out numeric and / or multi-media keys. For the mass market, that's possibly a more popular combination than touch + QWERTY. I happily admit I'm probably in a minority wanting QWERTY, after all.
I'm looking forward to getting my hands on the N97. For me, touch + qwerty sounds like a good combination.
