First, @Cecilff2:
You only need Steam for activation, not to play. You do not need to download Skyrim if you install from disc. If you want patches, you may need to download, but you could also contact Beth's support line to see if they would mail you the patches. They used to do so and you are a customer. It never hurts to ask.
Now, for some helpful suggestions.

General
The UI needs to be redesigned, especially on PC. However, such a redesign could even help the console versions of the game.
Only including a basic alphabetized list is not sufficient for proper management of the various areas of a PC. This is particularly true for Beth's games because of their choice of very odd naming schemes. For example, they choose names for healing supplies that do not align properly as an alphabetical list. I have no idea what they are thinking of or how they are playtesting, but I have yet to meet an RPG player who does not group similar items together in one category and then lists them in hierarchical order based on strength within that category. This is true for weapons, apparel, potions, med kits, and any other type of supply. My observation comes from playing RPGs, both pencil and paper and electronic, since the original D&D and AD&D, as well as adventure games on teletype machines.
Related to this redesign is the inclusion of an "Enchantments" item in the Magic menu. Beth uses a new system in Skyrim where you have to disenchant an item before learning an enchantment. Therefore, you need to be able to see the list of known enchantments whenever you are shopping. Of course, we cannot see the list right now because we have no option to do so EXCEPT when we access the Arcane Enchanter. Any player is almost certain to wind up buying items the PC doesn't need because the player thought that the PC still had to learn the enchantment, only to discover that the enchantment is already known. You might also accidently sell off an item you loot because you thought your PC already knew the enchantment, only to discover you were mistaken. My PCs know what they know and what they do not know, so this is really silly and very annoying.
The redesign extends to the Favorites menu, too, because I strongly suggest that Beth's UI developers go back and play Half-Life to see how an excellent UI is implemented based on categories of elements plus scrolling through individual elements within any category. For example, Favorites should bring up a short list of categories (perhaps 6 or so) such as weapons, apparel, potions, etc, and then choosing a category would list individual element/items (not just alphabetically, but by strength or perhaps most commonly used). As it stands right now, you wind up spending too much time popping up the Menu screen in order to jump into Inventory (for weapons, apparel, potions, etc) or Magic (for spells), and then scrolling through alphabetized lists in order to find the things you actually use. If you use the Favorites, you have to scroll through an uncategorizedd list of all elements you may use from time to time or very frequently, and everything in between. If categories were in Favorites, it would greatly simplify and shorten the time spent in menus and cause much less gameplay interruption.
