According to the reviewer, the only bad thing about the phone is that it hasn't got Wi-Fi.

Isn't it a bit too large to make phone calls on, though?

Nope. It's not much bigger than quite a few phones currently on the market; for example:
Nokia N95: Length: 99 mm, Width: 53 mm, Thickness: 21 mm
HTC Dual: Length: 107 mm, Width: 55 mm, Thickness: 15.8 mm

Mine arrives in a couple of days

I would have bought 100% if it had wifi. Unfortunately without wifi I'm not interested
