Must say i think Apple is the way forward. Up until around 8 months ago, i hated Apple and said i would never buy any of there products but after trying someone else's MacBook, it really made sense to get one so i bought a 13" Air. Had not trouble what so ever with it which i know i would have if i bought anything but Apple.
At the time i had a HTC Desire HD, yes it was quite a good phone but after about 6 months of use it started to slow down and freeze a lot so i decided to go for an iPhone 4s, best thing i ever did. For me having a Mac, they sync with each other great and are very easy to use together. The quality of the phone is far better than any other phone iv had too.
If it was down to me, id choose the 4s, really dont think there is anything that will rival it at the moment.
