Amazon UK is taking pre-orders for the WiFi-only Samsung Galaxy Tab P1010, with the 7-inch slate expected to begin shipping on March 31. Priced at £299 ($477), the P1010 is £100 less than the unlocked, SIM-free 3G version that has been on sale for several months now. Last we heard, the US launch of the WiFi-only Galaxy Tab would take place on April 4, though currently the slate is nowhere to be found on Amazon US. However, the dates certainly align, suggesting Samsung's cheaper version is finally ready to make its debut. Although Samsung reached the market quickly with the original Galaxy Tab, it faced significant criticism over pricing. US carriers had demanded that the voice-call capabilities be disabled, and sold the slate with a data contract (generally lasting two-years).
