What do I want from a tablet?

What do I want in a tablet? - apart from the obvious (infinite battery life, light weight, decent size screen, infinite storage)....

for personal use:

• email
• eReader (flexible on format and comfortable to hold)
• rss reader (and offline as well)
• maps  (decent quality mapping with gps and track recording)
• plenty of storage
• ability to edit word documents (.docx) and excel spreadsheets
• something like One Note for odd notes
• sync with desktop PC(s)
• Bible with different versions (I used Laridian on Windows mobile)
• Password manager

for work purposes:

• Ability to read technical documents / text books  (this means a decent size screen and PDF format)
• Remote desktop to windows servers
• Ability to access sharepoint systems, including sync for offline use (and edit)
• Sync with work calendar and contacts

In the past I have developed quite a lot of code for my Windows mobile devices - I'd need to replace or redevelop these on the new platform.  My apps include:

• Sharepoint client tool
• Offline railway timetable tool
• Mapping and GPS tracking program
• Code changes/bugs database
• Railway database
• Program for learning / testing German language
• Tool for noting railway track layouts
