I eventually cancelled that one order, they stated that they didn't know when the colour choice would be available (I'd only selected a different colour as it was listed as a no cost option), and I'd had a couple of "new delivery date" mails. Customer services were dire though, utterly useless. But then they were fairly typical off-shore, working off a script ....
Raised another one now, effectively cheaper - Z530 is now standard (yay!), so only optioned the 6 cell battery and a 16gb memory stick. I remembered that I had a Hauppage DVB-T stick bought a few years back that'll (hopefully) be as good as the now non-available built in tuner.
Even so, its basically going to be 2 weeks from placing the order to receiving it - thats an inordinately long time by current manufacturing standards?
