Until a few days ago I paid almost no attention to any of the pad type computers. I had an oppurtunity to briefly play with a Surface in Best Buy and I realized it seemed to run a standard version of W8. If this is indeed correct, it might be a good candidate for replacing my laptop that I rarely use because of its weight and size. So, please help me with the following questions: -Most important, can "Classic Shell" be installed so the interface looks and behaves exactly like W7? This is a nogo consideration - I will not use W8. -Is W8 64 bit so all my 64 bit programs work and I gain the added effiiency of 64 bit over 32 bit software? -Will it run my standard 64 bit versions of MS Office, Quicken, Mozilla Thunderbird, Teamviewer, iTunes, Paperport, and the Kindle reader for PCs? -Can the RAM be expanded beyond 4 Gb and is there even a need to do so? -Does it have a USB port? I saw no reference to one and this is important so I have access to USB memory devices. -Can it be charged using a standard 2 Amp USB power supply (so I can easily charge it my vehicles, use my backup battery to charge it, and not have to carry multiple power supplies with me)? -Is it safe to assume the 128 Gb of storage cannot be expanded? 128 Gb might be too limiting but not sure yet. -I assume a virtual keypad appears like on the iphone. What are opinions with respect to the practicality of this virtual keypad? I am hoping the surface can be configured to function like a very light weight slim laptop that provides all the functionality (albeit with a smaller screen) I have with my laptop but without the bulk and weight. The idea of having a touch screen W7 interface also appeals to me.
