It's a valid point - the delete button on texts is close to the exit button - but it's not that often an occurance. I've done it once or twice, and it has an awful habit of happening when you're rushing a text. All it means is you go back to 'new text' and it gets the text back up for you. If you set the shortcuts up properly it's just one more click.
This phone.. I've had it since it came out. Amazing. I think you all know the pros, so I'll focus more on the cons.
The lack of expansion. Yes, I know it has 8gb, but it's older relative has expension and can thus have 16gb of memory. Surely that's a step backwards. Also, this memory is just a built in memory card. It's a bit confusing when you first get it and it asks whether you want to be saving to phone or memory card memory. No biggie, but I have to be very picky to fault this phone.
As for a point which genuinely annoys me. It's touted as a multi-media phone, and it lives up to the name, but watching movies is very difficult on it. Sure, the backlight stays up, it fills the sharp screen as you'd expect, but unfortunately there's no way to pause then return to a movie. Better hope you don't get a call or text while you're watching it!
Also '6000 tracks' is a huge overexaggeratement. You could fit 6000 if you bought them all from 3's download service, but that's slow, clunky, expensive and bad quality. A song at 1mb is obviously not worth it. I have decent quality tracks, and can fit 1400 tops. I have 700 and a few movies, the entire first season (40-odd episodes) of Spongebob Squarepants, pics etc. The pictures it takes are large in size (100-700mb usually).
The sports mode capture is sublime. I adore it. I got some really professional looking pics of the fireworks through it. You just snap and you get it. The camera really makes it fantastic.
I also find it better than the N96. Definately better than the iPhone!
