I am brand new to tablets, but largely due to this site and its forums, I've decided to buy a Toshiba M4. I tried out a R15 at Circuit City and enjoyed it. I've just got a few questions about the M4 before I place my order, and I figured you could help me out. I plan on using it mostly for sketching and graphic design, and I've seen Wacom's Pennable technology always recommended to artists. This is why I decided against the cheaper Gateway, but I wanted to make entirely sure: the M4 supports Pennable, right? I'm also getting a Bstrong shield. Do these affect pen sensitivity? The M4 on Newegg (which I'm planning on getting) comes with 512 MB RAM. Looking at a M4 spec sheet, I see Kingston makes it. What I can't figure out is what RAM to order on Newegg if I want to buy another chip. Here's the product page: http://www.newegg.com/Product/Product.asp?item=N82E16834114178 Any help on that? I'd like to order a memory upgrade when I get it. Thanks for your help.
