The one thing most of you will have encountered during your experiences with android is how bad, laggy and sometimes not even working the preloaded market is. That is why I have put together a list of market alternatives for people who just can't stand it.
Slide me is a well set out, simplistic market that runs way faster then the original. It doesn't have as many Apps but it's a decent alternative. A great feature of slideme is the compatability button which lets you know if your device can handle the chosen app. It is free and you can download it off www.slideme.org
The Amazon market is a great alternative and probably has the most apps out of all the 3rd party markets. Another good thing about it is Amazon, in a desperate attempt to get people to use it, are giving out a free, usually paid, app a day. The only problem with it is you have to have an Amazon.com account which takes a while to set up.
Possibly the best way (in my opinion) to get apps is to use a service like androidzoom.com to browse the whole android market from your PC, get the name of an app you think looks cool a.k.a waveblazer. Then, search up on Google the name of the app followed by 'free download' and it will come up with many download links to directly download the .apk.
Obviously from this article there are many different ways to get Apps and games from different sources but if you are ever buying apps I would reccommend buying them off the android store to prevent the risk of your credit card details being stolen and also to support the developers.
