The past several computers I have purchased for myself were from Dell. While Dell is far from perfect, their shipping has been excellent with orders arriving days before they were promised. What can I expect from HP? I ordered my TX2500z on 9/8 and was given as estimated shipping date of 9/15. I just checked the site and it still says the unit is in production with a estimated shipping date of 9/15 (yesterday). When should I realistically look for my Tablet to arrive?
