Google have released an app which now let you browse your favourite catalogues all in one place. The app is tablet specific so it won't work on your Android phone, you will need an Android tablet running Honeycomb or Ice Cream Sandwich.
You can flick through apparel for men and women, including furniture for your own home. Once you've found something you like you can purchase it right from your tablet, no need to get on your computer.
From personal experience I've found that browsing for goods on a tablet is a lot easier and more engaging than on a computer. It's overall more fun too. Also images are usually of a higher quality to make use of the large touchscreens.
