In addition to that you don't really know what the market it going to look like 2 to 3 months from now when this ships. Apple, Asus, Dell and others could very well have a tablet in the market by then. So even if you were willing to chance losing your money entirely it wouldn't make sense to buy one of these.
The only payment option seems to be PayPal. Does anyone know what kind of buyer protection PayPal provides in case the payers never receive the device?
Careful - it looks like no protection. Italics mine:
> 13.2 What are the eligibility requirements for PayPal Buyer Protection? You must meet all of these requirements:
Use PayPal to purchase an eligible item
Pay for the full amount of the item with one payment. Items purchased with multiple payments – like a deposit followed by a final payment – are not eligible
Open a dispute within 45 days of the date you sent the payment – then follow the online dispute resolution process described below under Dispute Resolution
Keep your PayPal account in good standing
