Fancy OS with lots of nice features built-in and fancy eye candy is all very well, (we already have that with the various manufacturers custom interfaces ontop of win mobile) but what's been the main issue with win mobile to date is that it doesn't function solidly as a phone. Sort of like phone functionality is just a bonus rather than the primary function. Sure, the phone functionality has improved over time but still not good enough for most, barring perhaps the small minority of gadget freaks, who tolerate it purely because of it's convergence (myself included). What we should hope is that Win Phone 7 will once and for all address this crippling shortcoming, cos methinks this will ultimately determine whether Win Mobile will succeed to gain widespread adoption by the masses or simply remain a wishful enthusiasts pursuit.
