Yep that's the impression I got watching and reading dozens of reviews and opinions, sooner or later throttling occurs if you use it to do some kind of heavy task. I ended up buying a brand new SP2 with 8gig/256gig SSD over Amazon Germany for 700€ which I think is a great deal. And if I can't get used to it as a tablet I can always sell it, probaby for more than it cost new, and pay the difference for a SP3(or SP4).
