And reception of mtn?
which one is faster, cpu wise?
The P605 is faster. Even though the other has 8 cores in total, it's actually 2 sets of quad cores, and only 1 set of quad cores can be active at a time. I read somewhere that the technology is available to use all 8 simultaneously, but this ability was turned off due to overheating problems (so the technology is not stable).
Also, it has been reported that there is some sluggishness when the tab switches from using one set of quad cores to the other. I'm not sure if this gets fixed with the software update (which SA hasn't received yet).
I would like to get the P605 on an 8ta contract, hopefully on that deal that includes 5GB on-net data. I'm currently waiting on an 8ta contact to get back to me.
If that doesn't pan out, then I am strongly considering getting the P605 from MTN on contract. See here:
https://www.mtn.co.za/Documents/MTN_Yello_Trader_31Jan.pdf (page 15). The LTE version for R439pm with 2GB pm included data is very attractive.
Good luck with your purchase, and let us know what the device is like when you have it.
EDIT:
ps: I wouldn't bother with a 500MB contract for this device - if you're gonna use it fully, you're probably gonna need more than that (in fact, even 1GB is a bit skimpy).
