Paul Thurrott's SuperSite for Windows: Hands on with Google Pack: Conclusion from the first detailed review I've come across:
"While virtually every computer company on earth is scared to death of Google, and virtually every PC user seems to be in love with them, Google Pack serves nicely as a reality check. Not only is Google human, buts the flaws in Google Pack suggest that this company has a long, long way to go before it can ever justify its insanely lofty stock price. Google Pack is a mixed bag of applications, some useful and some not, though virtually all are deficient in some way as packaged here. I applaud Google for trying to make the PC experience simpler and more secure, but shipping out-of-date security products is even worse than not shipping them at all, because users will get a false sense of security and believe they're protected when in fact they are not. Google Pack is still in beta, so the more glaring issues can be fixed by a final release, if there is one. But this initial version of Google Pack is an embarrassment to the company. It's just a mess."
