My experience with Microsoft Surface RT

I wanted to share some goods and bads about my experience using the Microsoft Surface RT tablet.

First the tablet's hardware is great, I like the touch cover, kickstand, USB port, micro HDMI port. To get all these on other tablets you need to pay a lot of money for accessories. They are all included with Surface. Great stuff.

The wireless performance is very good, I can watch HD movies over the network from my WD live media player and it is working great. This does not work on my son's IPAD 2, I cannot compare with the newer versions. The wireless router is Linksys E2000.

The only problem I see is the lack of applications and hopefully this will be solved in time. I also wish MS would allow other browsers like Chrome. IE 10 works fine but I cannot see my browsing history, bookmarks etc from my PC or android phone.
