Most 17" Sony notebooks are only 1-2 hour battery life.
We are actually stocking the S model at John Lewis when it is available, along with a Toshiba G30 with HD DVD-ROM drive, (DVD burner combined, but no HD DVD burning). We have asked to trial both at our branch in Nottingham.
I can see the MacBook Pro 17" following with similar specs further down the line. If Sony can do it for £2000, I expect Apple could do it for a similar price within 12 months. I also expect a lot of these features to find their way onto the Mac Pro when launched either as standard or options, (really the only one missing off the PowerMac is Blu Ray). I'd of course like to buy an iMac in about 12-18 months time with digital TV tuner and Blu Ray for a fairly standard price too, as this would fit in with my purchasing timescale.
