E-Commerce's best "checkout, wallet" service

In the last 5 years e-commerce has drastically risen through the purchase of goods and services on the internet. It has become so easy to shop and browse for goods from the internet cafe, the office or the comfort of your own home. This brings up a question, which e-commerce service is the best? Today I will describe and analyse the 3 most popular sites: Google Checkout, Paypal and Microsoft Wallet.

Google Checkout "Wallet"

Google Checkout is now known as "Google Wallet". It was fairly easy  to set up and also connects to all other "Google stuff" (ie Gmail, iGoogle, and Blogger)with your Google account. You connect your major credit card or debit card and then you are good to go! I have not actually bought anything from Google's "Wallet" but if you can imagine, if it's like anything like Google's other products, it will probably be very simple and easy to use. Google Wallet is also integrating into smartphones as well. The smartphone app will in theory substitute from a physical wallet. this would be a great innovation but it is not plausible until more companies will gain the technology to use the app more widespread. 

Paypal

Paypal is the e-commerce I have most experience with. Paypal was bought out by eBay and is the exclusive e-commerce service for the popular auctioning site. Paypal is, in my opinion the most secure site out of the three since it adds and takes away money upon setup to confirm your account, on the downside, this may take up to a couple of days to do. Paypal also lacks in its mobility. There is the paypal smartphone app, but it is very poorly developed and not very user friendly.

Microsoft Wallet or "Live ID" or "Account"... not sure

Microsoft from my 20 minutes of research is going through an identity crisis with its naming for its checkout processes. I tried searching Microsoft Wallet and it directly linked me to Windows Live ID, which i had heard of. Live ID is a personal account to be used with Microsoft's emailing system and also the popular gaming console XBOX 360. From what I can glean, Microsoft will be unveiling all of these as one in which it will call Microsoft Account. Overall very confusing but typical Microsoft...
