WHICH OPERATING SYSTEMS?????
I know it will not run on win98 or ME,somebody better change that.

Product is good, the customer service at amazon is lousy!!
I bought autocad lt 2005 from amazon.com. It arrived when it was supposed to. I downloaded the rebate form from amazon.com and upon reading it, it said that the invoice must have the serial number on it. My invoice from amazon has everything except the serial number on it.

After 3 e-mail attempts to amazon to get an invoice with the serial number on it, I have given up. The response on all 3 was the rebate is between you and autocad, contact autocad. I contacted autocad and they said they can't accept an invoice with out the serial number. So, if you think you are going to get a rebate after you buy from amazon, think again. There is no telephone number listed on the website, so you can't actually talk to anyone, All you can do is exchange e-mails with someone in a foreign country who doesn't understand much english.

If I had it to do over again, I would buy this from another retailer.

Some nice upgraded features, but major headaches added
A little known aspect of this product is the fact that Autodesk will only allow LT to plot one drawing at a time (except for dwf files). This is a MAJOR hinderance. The layer command is slow and sheetsets and fields are unable to be created. The old LT versions were basically 3d disabled, now the drafting features are being removed/disabled as well. If your going to spend the money get autocad full or look for another product, we are very unhappy with this change, especially how it was not very well publicized and we didn't find out until we purchased enough for multiple offices and had it installed.
