For living room use, you'd struggle to see the difference between 720p and 1080p on a 42".
A full HD branded 40" LCD is now selling at R8000+. This is R2000 cheaper. That's very cool.
I disagree, I think you'll definitely see the difference on a 42". I agree the price is great, just thought I'd caution any prospective buyers to bear in mind the low resolution.
