• الف) امکان مشاهده شکل نهایی تا زمانیکه ایمیل مورد نظر را دریافت نکرده باشیم، وجود ندارد.
• ب) اعمال تغییرات جدید به این فرمت رشته‌ای مشکل است. همیشه استفاده از ابزارهای بصری برای بهبود کار کمک بزرگی هستند که در این حالت از آن‌ها محروم خواهیم شد.
• ج)اگر تغییر رسیده جدید، درخواست اضافه کردن لیست پرینت‌های قبلی این شخص بود چه باید کرد؟ آیا جدول مورد نظر را باید به صورت دستی ایجاد و باز هم به صورت یک رشته به این مجموعه اضافه کرد؟ در این حالت از کنترل‌های استانداردی مانند GridView و امثال آن محروم خواهیم شد.
• د) هر بار تغییر، نیاز به recompile برنامه دارد.
