Im doing all my work from home to..
Using a Thinkpad T23 and logging into the work server via my DSL, works great. If im on holiday or at my cabin i log in using my cellphone (i only need to transfer small files and e-mails)
Been thinking of upgrading to the T40 but this one will do fine for another year. The thinkpads are truly great laptops and IBM has EXCELLENT support services.
