I am more likely to build one (had a look on ebay earlier, and wow, so many built units for sale). I would build one and keep it for several years, and I think these guys build to sell at profit possibly - fair play. They are getting better units opposed to shops.
I will build a pc in the imminent future. Build a unit that can outlast the age of my phone lol. And that SE you have - a mate of mine had it at college at the same time I had a Nokia 6600. At that time mine was a 60 series smart phone and his was a IQ smartphone or something. I had IR remote (control for anything) and the likes, just shed loads of bad ass softwares. He had a few amazing softwares too but I think mine was more better, oh, and more compact lol!
