64-bit?

I'm looking at purchasing my first Vista machine and my first tablet PC.

I am looking at a HP tx2110US model with an AMD Processor at 2.1 ghz, 3gb RAM, and a 64-bit processor and version of Vista Home Premium.

My question/concern lies within the 64-bit factor...I am unfamiliar with the actual difference between 32-bit and 64-bit and just wondering if having a 64-bit processor/OS could run me into any problems with software compatibility?

Any suggestions/comments would be greatly appreciated.

What do you plan on using the tablet pc for primarily? More specifically is there any particular software you plan on using that you are curious about compatibility?

I plan on using it for college.
So I will be installing Office 2007 Professional Plus and OneNote. As well as various applications for the college network, such as Sophos and Pharos Clients.

64-bit is mucher better than 32-bit as u all would no

Before you go the x64 route, you should confirm that the "Sophos" and "Pharos Clients" software you plan on using is x64 compatible. Otherthan that, I'd recommend Vista x64 any day of the week.

Oh, and rather have 4GB ram put in your new machine...

64-bit is better for advanced hardware. Getting it work with with older software can be a pain.

From what I've been hearing, it definitely sounds like 64-bit is better than 32-bit...

My only concern is whether or not I can run all necessary programs/services/drivers in 64-bit????????????

I did contact the IT department of my future college and they do not typically deal with 64-bit and were relatively surprised when I mentioned the fact I am even considering getting a 64-bit processor/OS on a tablet PC for college

If you are refering to Sophos anti-virus, I remember reading a while back it works with x64, but like Dzomlija said you may want to comfirm that and Pharos.

Do 32-bit so you can get support at college. You don't need problems with your computer.

The only thing is the laptop I'm looking at is on a really good sale, pre-built.
