The One X for $800 is a great deal, I paid more than that to import with no GST. The GS3 will be $200 to 300 more expensive. But if cost is no object, wait another week and try out the GS3.
The SGS3 is only $149 more expensive @ $949 at Warehouse Stationery too
Tough call though, I think the One-X looks better, but the GS3 looks so far to beat it in every respect. I will however have both next Tues/Weds, and I'll be keeping both ;)
Time to sell the SGS2, and SGS1 though...I will miss them both
