I too am in the market for a HP tablet. Unlike my friends down south in the states, I have to settle for retail tablets that come pre-configured. But even in this case, I still have a choice between Vista 64-bit and 32-bit, and for the past few weeks I've been contemplating which one to get. Seems to me that 64-bit has been initially (and some would argue continue to be) plagued by software-compatibility issues, but most have now been solved. The consensus(?) seems to be that the 64-bit Vista is now much more useful and stable - is this true? The 64-bit model that I can buy comes with 4 gb of RAM, while the 32-bit comes with only 3 gb. If 64-bit Vista does in fact use up an additional 1gb of RAM, then in my mind I might as well go for the 32-bit and save myself $50. Furthermore, it seems to me that since the laptop is physically limited to 4gb of ram, there's really no incentive for me to get 64-bit anyway. In addition to the extra RAM, however, the 64-bit model also comes with blue-tooth, and an extra 70gb of hd space. However, the 32-bit comes with OneNote, while the 64-bit version doesn't come with anything, but can have Office 2007 + OneNote 2007 installed for an additional $100. What should I do?
