I'm kind of in the same boat really.
In the past year I've owned an MDA Vario 2, MDA Ameo, Nokia N95, MDA Vario 3, LG Viewty, N95 8gb, Nokia E90 Communicator...and guess what: I went out and bought an N95 classic again a few weeks ago and it's easily my favourite.
Vario 2: Too old; needed replacing
Sony-Ericsson K810: Good camera but a creaky case and limited applications owing to very basic OS.
MDA Ameo: too big, too glitchy, poor speaker quality. I used to get laughed at in public, but I did keep it and use it in-between phones until recently as I liked the big screen.
Nokia N95: glitchy owing to early firmware (camera too slow, out of memory errors)
MDA Vario 3: flimsy, rubbish camera and by this stage I'd gone off Windows Mobile slightly. The QVGA screen is not as nice as that of the two N95s, despite being bigger.
LG Viewty: for a few days in which I got frustrated with the temperamental camera and slow input method. Then I found it was blocked and swapped it for....
N95 8gb: Looked and felt nice at first, then I got fed up of the slow data transfer rate of the internal flash drive and started to long for my fiance's lighter and SDHC-capable classic (such is life)
Nokia E90 Communicator: I really like it, but it was just too big, considering that I usually have an EEE pc with me anyway. There was also the signal glitch - whereby if you put your fingers in the wrong place in open-clam mode the signal drops out. Poor placement of the receiver there I think Nokia.
.....and it crashed a lot....
.....and Nokia seemingly think the 'business' people who allegedly go for these phones want twee, windows 95 backdrops and boring-looking media players and menus - not so Nokia.
N95 Classic: I'm sticking with this for now, it's got the best camera on the market, it's small and now I've got Garmin XT all my Satnav needs are met. I also have a bigger viewing size for Youtube videos than on the E90....I do miss that keyboard though!
