That is a failing of basically ALL touch screen phones, although adnittedly some are better than others, because they have a resistive touch screen as opposed to capacitive ones (like the iPhone and now the HTC HD2) but that is starting to change
I disagree tbh, my Tocco has not failed at all on this feature, the touch screen was a blessing in disguise & I've had it for a fair while now interms of lifetime of the handsets in the market, also other touch screen phones around at the same time worked a hell of alot better, I had an M600i for ages from SE, the touch screen on that worked shockingly well & far better than the HTC & that was around alot longer before HTC touch phones, one of the original touch phones aswell, it was so good I bought a new one & held it in reserve for any issues on my main one, only sold it recently as the Tocco has proved to be very reliable.
The only issues with the Tocco which seems to be also related to iPhone was the losing all signal/poor signal/3g crap, all the same issues the iPhone had at one stage, possible they shared a chipset, I hassled Samsung UK who admitted there were problems with all networks, gave me a free camera & another handset the Omnia that tbh was absolutely shyte as phones go, res was useless, they had a mouse built into the touchpad thing, thats all I can call it tbh as was useless, so sold it, camera was useless so sold that & stuck with Tocco & got firmware updates which resolved the issues 100%, since then has been a dream phone as such, interms it just works.
Found a site that has number of firmware updates & all have been very good, officlal ones aswell.
But Samsung UK are useless overall, took them 3-5 months to fix the very well known Tocco network issues, but as I said now I would advise anyone to use it, cant fault it anymore.
Also I'm no Mac fan, but you cant deny whatsoever the iPhone does work well aswell, the touch screen is very good, even the iTouch I had for tunes ages ago it just worked perfectly, the app store is sheer brilliance interms of an idea, so many apps could be of use to so many people & revenue for a small developer, well to a point when apple cough up the revenue earned as this has been an issue, but overall I give Jobs kudos as it has done very well, pity they as you say charge for things that are already built in & not turned on, like the 802.11N chips built into macs that they charged a fee to enable, absolutely shocking way to conduct themselves, should of been free *** given the cost of macs.
