Mobile Burn a have a fairly positive review (http://www.mobileburn.com/review.jsp?Id=604&source=HOMETOP) of the SX1. They also are not convinced about the keyboard layout.

Intriguingly it finishes with the following statement.

With the "SX2" announcement right around the corner, I would hazard a guess that the future also looks great for Siemens Mobile.

Yeah I spotted that to... Wonder if it will be announced at the CeBIT show this week!.

SX1 has done very badly in the UK, mainly because you just cannot buy it on the high street, and no telephone operators support it. :(

I would have bought the SX1 back on the 8th of December when it was released, but I have absolutely no intention in buying it now. Especially compared to some of the funky phones coming out this year.

Siemens have really made a mess of their first Series 60 phone, I have lost all confidence that they will do any better with the SX2. :(
